Usually x264 rips are available faster than x265, due to slower encoding time for x265, so depends on how long you want to wait vs download time and HD space.

The sites that I see get x264 first, then x265 of the same shows some hours later.

nyaa for anime

sukebei.nyaa for nsfw Japanese media

no account needed for either of those.

I still run official eMule on Windows 10, even though it hasn't been updated in 13 years.

I understand that aMule, a fork of xMule, has relatively active development, and was last updated 2 years ago.

Limewire is gone, but ED2K is very much alive, and pretty darned good for finding older files.
