If you really had "all bases covered" you would not need three turntables.I currently have 6 turntables (5 in use). I’m clearly off base! Then again, I have 4 complete systems. I rarely use the turntables in two of them, but am glad they are there when I want to listen to them. One I use mainly for play grading my records when I put them on Discogs. I’ve been slowly doing that just so that I have an inventory of them.
The two currently in my main system are both direct drive turntables - a JVC QL-Y66F and a Technics SL1200 MKII. I have the JVC set up with a nice cartridge for my pristine records and the Technics has a Shure V15 Type IV with a JICO SAS stylus for my less than perfect records.
The one in my bedroom is an old Realistic Lab 400 DD table. It has an auto shutoff feature so I can put on some music and not worry about falling asleep and having the stylus in the runout groove all night.
