1 old Macbook Pro 2008, and some newer 2009, 2012 (Retina) and 2015 (Retina obviously). All with SSD and more than standard RAM, all 15". My daughter will soon get the 2012 MBP, at the moment it has Monterey but I wonder if I should install a newer OS. Mainly for web browsing and school work (she's 11).
Will Sonoma have as good GPU support as Monterey? This MBP has Intel HD 4000 and Nvidia GT650m
MBP 2008 - Catalina
MBP 2009 - Catalina
MBP 2012 Retina - Monterey
MBP 2015 - Mojave (!) - yes, we want to run Iphoto and Aperture on this machine...
My desktop PC is on Monterey and Sonoma at the moment, but I prefer Monterey.
