I own a 2011 Ranger Z118 with Mercury 150 Optimax. It is great. I added an 8 inch jackplate and am playing with the height. I may have it a bit high now but ran 60 mph avg (up/down river) in 103 heat. If pricing is what really matters to people, the Nitro is much cheaper in price. I bought the Ranger for the resale value and all of the extras that came standard on it. My thought was to buy this size boat now and upgrade later but I love this boat. I have never ridden in another boat that was as easy to drive and had the ride that as soft as this boat has. If anyone has a Z118 with an Opti and JP, let me know what height yours is set at and the related specs... speed, rpm, prop etc...
Once again, congrats on your new purchase and have fun with it. After all, the fish do not know what your are in, right?
