Ed:

I have the Global Ultimate Bipe. I have an OS 50SX up front and it flies just great! Loops, rolls, inverts, verticals, just about anything you're capable of doing, the Global will do well. Once trimmed out it flies like it's on rails. Landings are smooth, slow and very predictable.

I'm sure the DP Ultimate is just as good, but I can only speak from experience regarding the Global.

I'm sure you'll be pleased with either one.

As far as building the kit, if you have the time and you enjoy building from scratch, maybe that would be right for you.

For me, I'd rather fly than build. The ARF's today are really getting better all the time.
