Boring 2-button frost DK vs. overcomplicated 1000 buttons Unholy DK?

I have always preferred the class fantasy of Unholy DKs. Never found a good rhythm playing them so I play frost.

Its not just about the number of buttons (I mained a feral druid for most of Wrath - was THE complicated spec then).

I wish I could play Unholy, I would never touch Frost again (except old raid clears)
