3d modeling software quality

I don’t agree with you, although I have never used the software quite a few people do, probably for a reason.

Software is your tool, and if you are a great artist you can achieve quality results with any of the well known programs, it is question of taste/perosnal preferences/studio which one to use.

What exactly do you mean by high quality assets? The FBX data??

Performance is a different issue, nothing to do with content quality.

Obviously you can find certain differences between applications, especially if one of it costs a fortune and the other one is free, but bashing it saying that it is unable to produce high quality content is simply disproved by a lot of amazing artists.
