I can talk from a programmers perspective… the framework feels more solid… albeit a little more restrictive (which isn’t a bad things in its own). Having a good framework can do wonders for code encapsulation and i just feel that everything i do is less clunky.
Now… i wouldn’t say it’s BEST… because things like missing Geometry shaders are starting to bite me in the *ss (but they can be done in .usf) but still, every plattform has it’s perks and it’s drawbacks
