Mono vs multihull

[Wylieh]

Hello folks, I am new to the sailing world so please bear with me. I'm looking to buy a new (to me) boat, and can't decide what avenue to go cat vs mono, the one big question that ways in my mind is in open sea if a cat flips it turtles but a mono may self right. In you're experience is this common, are the cats only for crushing in tropics ( calmer seas) anyway I'm not trying to offend anyone just had that question in the back of my mind and am hoping some real world feedback could steer me in right direction. Thank you!
