My minoura mag trainer has always been reliable.
The advantage of fluid trainers is they’re quiet.
The advantage of mag trainers is they’re consistent (fluid loses resistance as it warms up, so could affect zwift, TR etc).
TBH though my minoura is pretty quiet (compared to the cyclops mag it replaced), most of the noise seems to be the tyre and rear wheel. So I’d say mag, but if you’re breaking them I’d just get whatever has the longest warranty, or try a fluid and see if it is any better.
p.s. if you’re in Reading I’m thinking of selling my turbo and trying rollers.
