I have both in my 80g cube. 2 mp10's and a nero 3.
My MP's are about 7 years old and have nver needed servicing, other then the occasional wet side cleaning(like any intank PH). You'll find much more "complaints" and the need for servicing on a google hit simply because the MP's have been out for many, many years, where as the nero's have only been out a couple. More units in the hands of consumers means more complaints. Besides no one goes onto the net to say how awesome something is. They only post reviews when somethings sucks. So you'll certainly find many more complaints on the MP's then any other PH. Honestly though, if they were as bad as many reviews would have you believe, how on earth are they still being sold, and is considered the gold standard in PH's?
The MP's move way much more water then the nero, are slightly louder when turned up high, and of course no wire in the tank.
The nero on the other hand has a very small footprint, can be adjusted via an app on your phone(which is a huge bonus for someone like me that has to move several other things out of the way to get to the MP controller to change modes), much wider flow, but has no where near the GPH of a mp10.
In my biocube 29 I had 2 mp10's, so in your case I would do one of each. The MP for when things start to grow in and you need more flow, and the nero to cover those spots the MP doesn't.
I'm a firm believer in random chaotic flow. In my 80G cube I currently have 2 mp10's, 2 jebao pp8's, a gyre xf350, and a nero 3. All running slower speeds(I believe slower speeds prolongs pump life), but very random speeds, so I get very chaotic flow.
