To sculpt multiple things at the same time in blender I just merge the meshes, sculpt away, then separate by loose parts.
you have to be careful how/what you do ofc. But it works…
The reason like blender best, aside from the price point and licensing, is its extensibility.
anyone with a modicum of brain can come in and adjust whatever doesnt work for them with a script or a few lines of console code copy/paste.
Yes, maya has similar things - but not the price point.
Re the UV stuff, yes. That is very tedious at times. But if you learn to pin and unwrap it cuts down the time needed to UV even complex items by a lot.
