In my experience, Brother has consistently done a good job with macOS support. They seem to continue offering driver updates long after many of the units in use have likely been replaced. However, my entire experience with Brother has been with their b/w laser printers. Our first one worked for 13 years before suffering a mechanical failure.
I'm off HP printers and MFs. We had a HP6200 series for a long time that printed quite well except for one thing—its internal self-maintenance functions. Instead of doing them during idle time, the do them when you start to print. Sometime this takes more than a few seconds but, more often than not, takes a long time.
I thought this HP aggravation only affects old HP 6200-series multi-function devices. However, the museum where I volunteer recently bought a current HP MF printer for the information desk and it does the same thing. As a visitor was leaving they asked me for a hard copy of an online document and I hit "print." They had to leave before the HP decided to finish its maintenance routines and belch out the requested copy. So, no, still a serious issue IMHO.
