Here is a good review with accurate pros and cons IMO. I love 1P on Mac/OS X but on Windows I just EH OH ELL.

Dashlane vs 1Password
I didnt want to go into detail and compare the core or advanced features of these apps, you can find elsewhere. My goal was to find something more convenient and easier to use than KeePass but keeping the balance between security, functionality and convenience.
It was also important to me how trusted the vendor is, what kind of reputation they may have and how easy it is to get my data, should they disappear from the market.
This is purely my gut feeling / opinion and based on my quick and dirty trial based on versions available at this time of writing. I looked at how they compare to my current software KeePass regarding functionality, security, design, look / feel and above all, how easy the transition would be.
Dashlane pros:
offline or online: you only have to be online while register an account, it does not affect working with an already created local database if you choose not to pay or turn off cloud sync
secure: 2 factor authentication supported
clean interface: identical look / feel on both Windows and OSX
security and authorisation: even if you just want to create a brand new local valet (without cloud sync) on a new device, it needs to be approved with an online code sent to the registered email. Dashlane essentially tracks the devices associated with an account regardless you sync to the cloud or not.
browser integration: seamless plugin install and integration during setup
auto login: no need to click (most websites) on submit button ever again. If you happen to have multiple accounts for a single site you will have an drop down list to select from.
export: csv and its own encrypted .dash format
cost: subscription based, annual fee then you can sync your valet to unlimited number of devices including mobile
support: good although over email a bit slow
security dashboard: gives you warnings about reused passwords, compromised accounts, etc.
Dashlane cons:
icon view: I hated it, I dont need a thumbnail to identify an account, no detailed list like view. To see any details about any accounts I had to click on them individually
no copy item: I had fill new entry for few similar items even if 2 fields changed only
the interface: designed for web accounts only, not so useful for example PIN numbers where there is no username, it simply wont save without username field filled.
import mismatch: The account name and access URLs are really important for autofill, although I had some websites in the valet after import, on visit I got the popup offering account creation which indicated failed match against my valet stored entry.
idle lock only: no option to lock on screen lock, etc. although its not so much of a concern for an average user
import: KeePass import is Windows only, although works sort of well
no virtual keyboard: just some extra protection against key-loggers although not so much of a concern
main window: over-engineered, password categories does not help to organise accounts. Over 100+ accounts this view becomes overwhelming and confusing
apache authentication: incapable of filling / recognising apache like authentication popups
security: I didnt like the idea of having the ability to log into their website and browse my password valet (paid only)
logo: I just cannot personally associate antiloop with password management
1Password pros:
offline or online: no built in cloud sync option, Google Drive, iCloud, Dropbox, WiFi or just local valet, its your choice
design: love the application on OSX, similar to KeePass, easy to see details, password strength, etc. in a detailed like list view
main window: collapsible folder options, excellent organisation and tags, really nice looking interface
import: KeePass import allows field selection from the CSV export to mach 1Password fields which comes handy for complex entries
security: openly published security design
trusted: stable software from vendor with good reputation
support: great support and community forums
export: csv, text or its own .pif format
shared vault: could be very handy between family members
security audit: reports weak passwords, old or duplicated entries, etc.
1Password cons:
overpriced: no subscription and copies need to be purchased for multiple devices, mobile is also extra
Windows version: may be identical functionality wise but looks / feels totally different to OSX. Ugly, clumsy and suggest very early development.
browser plugins: install is not part of the setup, needs to be done manually for each browser from various sources and its convoluted / confusing especially on Windows
no auto login: no auto field population either, even a simple browser does that. I dont know why I have to hit CMD+\ key combination to be able to populate fields and log in automatically.
no virtual keyboard: just some extra protection against key-loggers although not so much of a concern
no 2 factor authentication: and its not even planned
browser plugins based on websockets: and it can break things or requires specific settings on some platforms , Windows especially
apache authentication: incapable of filling / recognising apache like authentication popups
Verdict
No clear winner for me, decided to keep using KeePass until something better comes along. The big shock for me was the apache server authentication, neither of them could handle those popups so I was left with cut n paste or save in the browser, which was a big deal as I have a lot of those.
I liked Dashlane (2.4.1) but it needs refinement, something that 1Password (4.4.1) has on OSX but it is very pricey and I dont think its justified compared to some of the missing features/ annoying bits. I also need at least Windows and OSX support, which is done well from Dashlane but 1Password is very much beta on Windows and I am not even sure, on what grounds they can charge money for it.
