The problems with GIMP, the last time I checked, were - no support for 16 bit, problems with color management, slow (photoshop is extremely optimized, and now has GPU support). Plus I hate the default UI - they need to redo it completely.

There's http://www.gimpshop.com/ which is gimp with a Photoshop-like UI

I think GIMP has had a single-window photoshop-esque UI built in since 2.8

Proper 16-bit support is the big thing for the next release and it's significantly less slow since it got multithreading support in 2.8. Still slower than Photoshop, though.

I've been hearing about the 16-bit support in GIMP for at least 5 years now. I will believe it when it gets released.
