I have heard multiple times from a friend who is an excellent pilot that owned a Classic for years and then switched to Ultra that he feels the UL flaps possible blank out elevator a bit if flaps are deployed aggressively.

Says he also preferred airbrake/flap combo that Classic version gave him as they made plane's sink-rate more predictable and he could land her at his toes every time. We fly at 5500 feet on 550-600 foot runway so pinpoint landings are more necessary.

I have flown neither and am ceratainly not an expert, however my friend who owned both had considerable stick time on them.
