I think Gnome 3 doesn't quite "do" polish as much as Unity. I am very fussy about fonts looking right, and I'm afraid that at smaller sizes, the font scaling in the Gnome terminal just looked wrong, whereas Unity is perfect in this sense. It's a tiny detail, but Unity kind of feels as polished as a Mac. It also has better dual-monitor support because you can independently set the font scaling for different dpi on internal/external monitor. Crucial if you run a high-dpi notebook in conjunction with a normal fullhd monitor. On Fedora Gnome I had ugly mis-sized title bars and UI fonts on at least one of my monitors. Second, I do CUDA development, and there are three Cuda 7.0 toolkits downloadable for Ubuntu 14.04 and 14.10 right now, but Fedora 21 is still "coming soon" and has been "coming soon" now for over 6 weeks. Deja vu a few times already on this. Moved back to 14.04, even though I loved the progressive ideas and clean look in Gnome 3. I still run Fedora on a cubietruck for fun: no problems, works well, but I use the e17 desktop which is a fantastic retro reminder of the 90s if you need an antidote to Jony Ive. It's fast, lean, unapollageticaly black, and terminology looks great and has some neat features for inline graphics if you're a terminal junky.
