Ricker Hmm...just my opinions, but:
1.) Amount of content - yes. Believe SLR stopped carrying scenes a couple months back from studios who did not permit their content to be included with Premium. So technically yes, there are fewer scenes. I've also noticed at least one other studio (VRConk) that has not had new scenes released in several weeks, might be others I haven't noticed. No idea if it's because that specific studio was bought by VRBangers or what.
2.) Resolution - nope. Resolution is most definitely the highest it's been across the board, at least with the more major studios. The exception is with many of the new smaller start-up studios joining so far this year, in which case yes- many of them struggle with video quality/resolution.
3.) Diversity - feel like this could go either way, very subjective. Again with getting rid of the pay-per-view only scenes, there is definitely a hit to the diversity of videos there, but I still feel confident in saying SLR still has the most diverse spectrum of scenes by a pretty huge margin.
