My preferences include mostly older footage, Japanese, and the odd "alternative" stuff.
Every so often I enjoy watching some of the classic English footage like World of Sport - lots of good shooters such as Billy Robinson, Jack Foley, the Riley's, etc. to come from that place & era.
Also, anything with Karl Gotch is worth watching in my book.
Today's indy scene is primarily a low-grade trampoline act with sprinkles of garbage cans, thumbtacks, and other "hardcore" niceties.
I don't follow any of it.
