I started with Cakewalk 8 - which I found very intuitive, but I wasn't able to get what I felt were good sounds (no fault of Cakewalk - the voices just weren't there at that time)
A few years later I tried Plasma - I found that very confusing
Then Cubase VST - hmmm - better. So I bought Cubase SL 1.0 - upgraded to 2.0
Just when I was settling in I tried a (ahem) version of Sonar 3.0. WOW! Everything worked. It was SO intuitive. Say what you want about cracks - but it made me buy Sonar 6.0, which I have upgraded to 7 this week.
I've given Steinberg about $3,000 - and I use none of it. Cubase, Halion (there's unintuitive!), Groove Agent 1&2, Virtual Guitar2. I repeat - I use none of it - it's not even installed on my newest machine.
With Sonar 7, Ez Drummer, Real Guitar, Real Strat, Guitar Rig and all (and there are many) goodies in Sonar, I can (after 15 years and setting up 4 different home studios) produce music I like to hear
Thank You Cakewalk & keep it up
