Yea, I intentionally restricted my post to the base tiers as gamepass has a similar schema since they both show similar featuresets at higher tiers.

I made a basic breakdown:

1. Basic
   • ps essentials: 11$/m
     • multiplayer
     • shareplay
     • save backups
     • discounts on store
     • monthly games selection valid for duration of subscription
   • gamepass essential: 10$/m
     • multiplayer
     • free game catalog: 123 [81 of which supported on Windows as well]
     • cloud gaming: 87
     • in game benefits in select first party games
     • rewards program
2. Mid Tier
   • PS Extra: 15$/m
     • previous tier
     • free game catalog: 409
     • ubisoft classics program
   • Gamepass Premium: 15$/m
     • previous tier
     • free game catalog: 572 [395 of which is supported on windows]
     • cloud gaming: 412
     • First party games promised to be on game catalog within 1 year of release (Call of Duty Excluded)
     • semi-priority cloud play queue
     • 2x reward points
3. Best Tier
   • PS Premium: 18$/m
     • previous tier
     • classics catalog: 163
     • game trial catalog: 260
     • sony pictures catalog (a movie/media streaming service)
     • cloud streaming
   • Gamepass Ultimate: 23$/m
     • previous tier
     • free game catalog: 909 [587 of which are supported on windows]
     • cloud gaming: 555
     • day 1 first party releases on free game catalog (Call of Duty excluded)
     • Free EA Play: 182 games + select DLC
     • ubisoft classics: 120
     • fortnite crew
     • priority cloud gaming
     • 4x reward points

This was just a somewhat quick list of info found online when comparing the two. I can see each tier being useful to someone, but I personally find that Sonys offerings for PS+ don’t stack to Gamepass, and that’s from someone who has been loyal sony fan since the PS1.
