What UPBGE version should i use for a comparison with Armory3d?

I tried UPBGE first, but got lost in the versioning jungle. All the examples i started did not work properly. Next i tried “Waiting for…”, which also did not satisfy my demands, mainly due to limited vert count. It gets really slow with larger scenes. Armory3D does better here, but the documentation is scattered and a real mess. However, most docs you need are there, just need to find them. It also has the best Blender integration so far. I made some examples which i would like to port to UpBGE for a direct comparison. If you have any suggestions on how to proceed here, i´d be grateful.
