Reliability will be more or less like any other sportbike out there. That is, it's likely to be pretty good. It's a "mature" design - it just hasn't changed a whole lot since, what, 2013? It will be far from a money pit. The 2-year warranty is nice on a brand new one, too.
Up-side is great mid-range power relative to the 600 fours. It's a smooth-running engine, too, not really vibey.
Down-side is, as a street bike, the ergonomics are fairly uncompromising. I think only the MV F3 and Yamaha R6 stand to be more "ass-up, hands down" than the Daytona. The CBR, GSX-R, and ZX-6R are ever-so-slightly less aggressive.
Deals on 2015 and 2016 models can still be had - $9000 to $9500 for the non-R model is what I'm seeing, so there's no really good reason to spend full-price on a brand new one. The 2017 model year version only comes in Ohlins/Brembo-equipped R trim... that's $14,000. Awesome bike and all, but yikes.
