There is the diplomatic debate between brand loyal owners, and then there is the pull out all the stops sports team argument! Lol����

How about production numbers, who is building more cats each year?

OK, here is my take on it.
First of all, production numbers mean nothing. They both build very few a year.

It is impossible to compare brand vs brand when even models within the brand vary greatly. For example, I had a 40' Skater classic that was probably one of the prettiest boats out there (IMHO), but I didn't like the ride. The 40SS and 388 though, have a great ride because of a newer, better hull and tunnel design.

For me, the switch from a Skater was because I liked some of the features and ergonomic layout of the MTI vs Skater, and I was looking for a better ride in the slop. Additionally I wanted to upgrade from 1100's or 1350's.

The best thing you could do is to prioritize your needs/wants/usage and narrow don to at least a size (width and length) range and then spend some time around the models I thin that range of different manufacturers.
Or, do what I did and buy one of each brand and see what you like best!
Nobodies opinion really matters but yours.
