This is nonsense, CATS is a perfectly fine toolbox like any other. You just have to use it when appropriate.

I nearly guarantee that most people bashing Cats still use its tools without even knowing they're a CATS thing, such as applying a shapekey as new basis, or applying a pose as rest pose.

Just *don't* use "Fix Model" for anything that isn't specifically an MMD model. Avoid material combiner and try to manually atlas instead. Other than that, you should be totally fine. There's so many useful tools in there that Blender lacks, even small stuff like merging a bone into its parent.
