Other than vaulting, you're smoking crack. The COH2 UI is so incredibly bad vs the original, reversing is a joke now and vehicles dance like they are having an epileptic seizure when you use reverse when in vCOH it was easy just to shift click back up.
The UI is mostly personal preference, of course players that played CoH1 for the better part of a decade would prefer CoH1's UI. I would agree with reversing, according to Cruzz vehicles consider queued move orders complete if they get within 25 meters of it, that needs to be reduced to at least 8. The pathing is a problem that people have always complained about, I went back and watched some vCoH casts a few months ago and people were complaining about the pathing then too.
Personally I rate the UI as overall superior. You get a unit bar, so you can always see the status of every unit without needing to visit them. You can reinforce large groups at one time as well, which is an invaluable change.
