For Blender you might want to check the Bforartists fork which has a way better UI than the default one : https://www.bforartists.de/
The Maya Config Addon for Blender 2.8 is another good UI that mimics the Maya one: Maya Config Addon For Blender 3.4
Although the Blender 2.8 UI is a huge improvement over the previous version it still is not as productive as it could be and those two alternate UIs can improve productivity a lot.
Then on the Blender Market marketplace there are many useful commercial plugins that can make it way better although some are a bit too expensive.
Then for PBR painting there is the cheap ArmorPaint https://armorpaint.org/
And another good software is Rocket3F Basic which is free while the Pro is not that expensive: https://www.rocket3f.com/
Anyway don’t expect a single software package to be perfect and that’s it, not even the very expensive ones really are. Some have better tools than others and buying additional plugins available can be very useful.
