Keep one thing in mind.

I am 6'3" tall, 210lbs, with size 13 feet and I use almost all the adjustment up on the Epic 18x sport. So if you are bigger than me you might want to make sure you fit, especially if you have feet bigger than 13.

I was torn between the two boats also, but I could not find a Qcc-700 to demo anywhere in Washington or Oregon, so I went whith the Epic and Epic usually wins all the races around here too, so I know it is a fast boat.
