I've no comparison to other rowers as I've only rowed on Concept 2 and older models (concept 1?), but it's an excellent rower. It's widely used by rowing clubs for winter fitness and there is lots of training data available. Therefore it is easy to compare your trainings to those of others in every stage of your fitness. I'f i'd buy a rowing machine I'd buy a concept 2. The one complaint you may have is that it's overengineered for a single person to be using.
And of course the noise, allthough the later generations are more quiet.
By the way, rowing on such a machine takes lots of discipline since it can be mindnumbingly boring or at least that was my experience*. You sound like a disciplined guy though, so that may not matter to you. If you'll proceed, I'd take some sort of rowing class or at least watch some youtube videos if I were you. The few times I've been in fitness clubs I've seen all sort of posture problems on a rowing machine.
*I've rowed between ages eleven and 22. The last 5-6 of those years I trained between 3 and 10 times a week, about a third-fourth of those trainings on a rowing machine.
