This is what I primarily use for 3D modelling. Getting used to Blender is a painful experience and I can only compare it to the controls in an aeroplane cockpit. I tried to cope with how bad it was, by exploring other options, but the other options inevitably ended up more limiting and limited.

Once you get used to it and its quirks, it's pretty good.

A nice piece of modelling software, primarily aimed at modelling for games like Minecraft, though you can use it for game engines. Its main weakness is the lack of good animation tools. It also sucks in some other ways due to a lack of shapekeys/blend shapes(useful for character variation). As a result, it's kind of eh... Not something that works well for anything where you don't want to spend a long time modelling, texturing and animating.

I have only used a trial version of this software, but I found it hard to use, but the idea makes sense. It's about making a 2D tileset then texturing stuff with that 2D tileset, but I can see it becoming a mess once you get to UV Unwrapping complex models.
