I like sites that are aggregators of content (no one site, necessarily). I think the best move is to find release groups you like the quality of and trust. From there, find out where they upload. I was a big fan of RARBG remuxes (x265) and RARBG-affiliated TV release groups, so it took a bit to find acceptable and consistent replacements. It’s worth the effort.
Who did you replace them with?
For movies, PSA slotted right in the quality/size hole RARBG left for x265 movies. There’s groups with better quality at higher filesizes (like QxR), but the ~2GB 1080p stuff PSA puts out suits my needs well.
TV is a little eh. XEN0N is where I ended up, but definitely isn’t on par with ION10/ION265. I haven’t found a great catch-all replacement. But I haven’t had to grab a ton of TV lately, to be honest.
