I really like my SuperSix Evo, I make pretty good power and can't detect any flex, def feels like every bit of power is going straight to the ground. It also climbs well, and has some aero touches so it holds speed really well for an all around/climbing bike. I've had 32mm GP5Ks on it that measured out to 34mm on wide rims with plenty of clearance. Did a seven hour, 123 mile ride with almost 9,000ft of climbing, and it was comfortable and fast, ride and handling are fantastic. Not as flashy as some of the bikes mentioned, but a really great everyday bike, imo.
