Controller tracking is nearly flawless, with some limitations like not being able to hold a controller behind your back or hidden behind your other arm, but I don't run into those limits in practice.
Probably won't help your glasses though. That's one of the Quest's bigger design oversights IMO, that wearing glasses can scratch the headset lenses even with the glasses spacer installed. There are 3d printed lens rim bumpers that will keep glasses from touching the headset lenses, but if your glasses don't physically fit that just trades smushing them into the headset lenses for smushing them into your face.
