I'm so long into it now, it's hard to think of any specific tips. I suppose I'd describe it like this.
Pre X-series, I used to have my hand constantly hovering over modifier keys, and I was pretty fast with all that. And when X1 came out, my reaction was a lot like yours: my awesome skillz were redundant, and everything was suddenly slower. But I got with it, and I really turned around. I acquired my current avatar somewhere in the midst of a long thread about this way back about five years ago. Started out as a hater, eventually became a high priest of the order :)
I think I'd say it's more a mindset thing. If you can get used to the whole thing about where the hit points are and so on, you'll find it taking a lot of stuff off your hands.
I will say this: I think Cakewalk never quite came out with a good "here's how this works" video, and what they did come out with was patchily linked and promoted. Sonar is really lacking a beginner's guide. I think they're starting to get better on that, but they've got a brilliantly designed, but under-explained, user interface, for my money.
