I am currently running a nitro 700 LX with the 115 merc and have been very happy with it all around. Other than general wear and tear maintenance I have never had any problems with mine. One of my buddys I fish with has a 901 CDX and has had some minor problems but mostly just motor issues with his 200 EFI merc. I have heard of people saying they dont hold up as well under harsh conditions .They say the hull will begin to stress crack over time although I have never experienced this for myself.
As far as the ride and handling of the bigger Nitros i don’t see much difference between it and the big Rangers.
I have always thought you get what you pay for but for the money I will probobaly stick with the Nitro for my next boat.
Just my experiences. Hope it helps you out.
