Love the Dunlop Roadsmarts I have fitted- best ever feedback in the wet and slippery stuff, but also mucho grip in the dry.
Funny thing is; whatever you fit they'll feel superb compared to your old ones (once they're scrubbed in) in anything except dry, hot conditions and so you'll think that sliced bread has something to learn from them.
And any differences in turn-in and sidewall rigidity are things you just get used to.
Unless you compare them back to back there's no real answer to this one, depends very much on what your riding style is, whether you ride commuting every day no matter what the weather or it's just for dry Sundays, etc, etc. And that's without how you ride it, do you get to the edges, or just the edges of the tarmac bit, how confident you are, how you use the power, whether braking stability is more important that handling and grip, etc, etc, etc.
Oh, and there's longevity, double/triple compounds help, and Avon (I think) do a warranty- if you have a puncture within the first 1 mm of wear they'll give you a new one- You'll boil your brain trying to get a definitive answer.
And lastly, once you've found your perfect tyres, when you come to renew them you'll find that the bloody manufacturers have brought out some new, even better, rounder, blacker etc alternatives so once again you won't know what to pick.
Sorry 'bout this; I expect you were after a straight answer

It's not falling off, it's an upgrade opportunity.
