Blender’s UV tools are considered by some, myself included, to be top notch.
The tools in Maya are cumbersome by comparison.
Check out the Blender Cookie video: http://cgcookie.com/blender/2011/01/21/intro_uvmapping/
And here’s a link to new tools added after that video was produced: http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.62/UV_Tools
The UV Sculpt tool is a personal favorite. I think only ‘Unfold3d’ has a comparable tool. And that’s 699.00 €
Speaking of ‘Unfold3D’, the so-called best and fastest UV map generator [according to their promo line], It doesn’t do a thing I can’t do better and faster in Blender. Truthfully, my unwraps are always better from Blender.
Yes, the UV tools in Blender are excellent, it’s the workflow where most people stumble. One does get used to it though.
