Modo indie is current version 901, and Modo 10 indie is coming in 1-2 months from now, so if i were you just sub for a 1-3 months then if you like it, you can buy Modo indie 10 for 299 USD(no need for subscription, assuming the price doesn’t go up), Modo 10 is more suited for game development:

Modo is pretty easy to used compare to blender(I totally understand how you feel about it’s UX/UI). Modo is like a modern version of Lightwave but even coming from 3DSMax you should be able to learn it easy enough. No one can truly say which software is best , different people different preference to UI, you need to take it for a spin by modeling something.
