I've been running the Dell U2715H since late November and would rate it very highly. I use if for both home (connected via DisplayPort to TB on my late 2013 15" rMBP) and work (connected via mDisplayPort to DisplayPort on my windows laptop). The touch controls on the bezel allow me to switch the monitor inputs back and forth easily. For home use I do photo editing, MS Office, browsing and some light gaming. Work is a lot of IT support over VPN. I use the USB 3 hub for an external SSD drive, a TM backup drive and syncing my iPhone and iPad. That hub is a nice feature. I looked around at a couple of other 27" IPS 2560x1440 monitors and coming from a U2414H UltraSharp monitor, this was a no brainer. I paid $529 USD when I bought mine which included a 10% company discount I had available, coupled with the holiday season pricing, but I'd buy it again in a second at the full price. My suggestion is to go see this or any other monitor you are interested in, in person if you can before you make any purchase.
Hope that helps!
