Been using Mag Drives since the 80s, One of the 1200s has been running 24/7 since then. I have replace impellers and volutes, mostly because an object got caught, this can happen with any pump, especially if sand can get in which pits and ruins impellers and volutes.

The pumps can vibrate/hum especially if sand or junk isn't regularly cleaned out.
I use sponge filter under the pump to lessen vibration
I also run a Laguna 2600, but for only a short time so far, so I cannot vouch for its longevity. The Laguna has been quiet, and supposedly uses less power, the only downside I have found is that is not set up for PVC fittings, which I prefer to flexible hose

I consider this my own fault, when it started to make noise, I didn't clean it out.
