The ergonomics are a lot better than the OG WMR controllers which was a surprisingly nice boost. The battery lasts longer too, and the haptics feel stronger as well. The thumbsticks can finally be clicked with the left menu opening the steamvr overlay and the right opening the ingame menu. The grips are analog too which are more comfortable when holding things and of course let you do more with them like sliding your hands in Boneworks. The tracking volume is bigger with the G2 as well thanks to the extra cameras, but that's headset specific. 

What is worse is the amount of inputs. The touchpads on the OG WMR controllers useable as five face buttons as opposed to the mere two the G2 and Oculus controllers have is amazing. The extra inputs are great for not made for VR games like minecraft, skyrim, modded Doom etc. Where the extra buttons really help. 

Both sets of controllers are backwards and forwards compatible thankfully.
