These two items are in no way comparable, but I would say iPhone.
Agreed w/ bpeeps. Other than the iOS and similar design aesthetics they're not really comparable.
To answer, though, I'd say get an iPhone 6S+ only because it'll give you the medium between larger device, and mobility of a phone.
Thanks.They are completely different devices suited for different needs. The question is what is your need?
You wouldn't get an iPhone primarily for video or web usage and you wouldn't buy an iPad to make phone calls or use as a music player.
Then I would have to say an iPhone 6S+ like someone else mentioned.
Watching TV, movies, and photo editing = iPad
Well considering how difficult actual calling can be with an iPad, I would say iPhone. It's more versatile and easy to have on you at all times. You mentioned a lot of media-heavy things so make sure you at least get a 64GB model. Photo editing will be more fluid on the 6S due to having more RAM but there are limited apps that let you edit. But that is also true for the iPad. I use Lightroom Mobile on both but they require using a desktop along with it to import RAW files which are then synced wirelessly to your device through Adobe Creative Cloud—I've got about 30,000 photos synced to mine. If you just want to edit photos taken on your device, then it can import those on device without issue and the editing is actually pretty decent for non-RAW files. It's also great at organizing. But there's also a monthly subscription. However there are also lots of other great photo editing apps out there if you don't need cloud syncing of massive RAW files. Furthermore, if you want to work with photos on your device then the 6S will give you a much better camera experience than an iPad and you're more likely to always have it on you. If you are really going to watch a lot of movies and TV shows then a Plus model would probably be best. As someone with slightly above average sized hands, I have found my 6 Plus to be pretty annoying over time and will be going back down in size to the 6S size tomorrow. So that part is really up to personal preference. A lot of people love the Plus. But if you need to decide between the price of device storage and display size, I'd definitely go for more storage unless you plan on constantly streaming media. As you can see there are lots of answers depending on your use case!
