To be honest I don’t know if this is the right place to ask such a question, but hey, let’s give it a try.
The game I’m currently developing is a 3D game but with a very “retro” style. For example the creatures in the game are just animated sprites instead of actual 3D models. However I want to be able to make simple 3D models as well for things like a building that you can enter etc. So I realized I had a license for Maya and I decided to try it. The first impression wasn’t very nice, the program took minutes to start. Once the program is running I am completely overwhelmed. There are just so many buttons and menus and other things that I will never have any use for. The next thing I did was to uninstall it.
I just want a 3D modelling program that isn’t too hard to learn and doesn’t have 100000 features that are completely useless to me. I want to be able to create models consisting of simple shapes, texture them and export them as .obj. I’m thankful for any suggestion that’s better than Maya. 
I’ve found Maya relatively easy for me to use for my purposes (same as you, mostly simple shapes with some textures) with just a couple tutorials. I would suggest that you look at some as well before you give up on something.
