It's all about currency and practice. I'm pretty rusty at the present so flying partial panel would be no picnic. However in training you have to faff about with compass watch and TC, in the real world you'll usually have a GPS for heading and track which makes life much easier.
So you can use the turn coordinator for keeping the wings in the right attitude, the altimeter and VSI for pitch and the GPS for heading/track which isn't too hard.
