One of several genres I like, is gangbangs.
Sketchy Sex & FratX were my go-tos for a few years.
But for vanilla & hardcore porn scenes, I loved Young Perps' early hardcore scenes, until 2022, when they switched their entire format and only do softcore porn now, so I stopped watching them and went to RFC.

So I tried Raw Fuck Club and it's a hit or miss (I love and prefer hardcore/rough sex which gets me off every time).

After YP and RFC, I basically found that any bottoming scenes from Jay Tee, Yoshi Kawasaki, Jkab Ethan Dale, Felix Fox, Darron Bluu, Cole Church, Duncan Ku, Kyle Connors (don't judge me), Jordan Lake, Tayler Slater, Landon Matthews and Mickey Taylor - and solo or topping scenes from Harry Lewis (of English Lads), are guaranteed to make me cum in less than 20 minutes (it usually takes me 45 minutes to an hour to cum). And rarely, I watch Rhyheim Shabazz too, since interracial porn is my favorite.

Some other porn studios I love watching (but haven't in awhile) are Sebastian Kane's studio in the UK, Hung Young Brit, Str8 Hell (absolutely my favorite English studio), Triga Studios (they're a hit or miss though), and Czech Gay Fantasy (their series of twinks bottoming in brothels has made me cum for so so long - my favorite Euro porn of all-time! And their porn flick, "Slaves" from BoyfriendTV is how I found their site & immediately subbed to CGF.)

I used to watch East Boys, but it no longer does anything to me (since the guys don't moan).
And I loved Raunchy Bastards, but Pierce Paris is never going to replace Clay and his amazing topping skills. (Raunchy Bastards was my favorite studio until a few years ago)
And last, three of my other all-time favorite studios (for my go-to BDSM scenes to cum to) are Missionary Boys (are they called Mormon Boys now?), Masonic Boys (separate from the former), Next Door Taboo, Family Dick and Men on Edge (Men on Edge barely uploads anymore, though; I still love their scenes with Van Darkholme participating in the sex, and I hate that he became more of a director when Sebastian Keys - who I also love to watch - got there.). Sidebar: Branden Forrest and Sebastian Keys are 2 of the best doms as well.

As for individual scenes:

1. Tayler Slater - Tag Team (from Young Perps) and his BDSM scene with Duncan Ku for Peter Fever (I can't remember the title). And his Duncan Ku bottoming scene with Peter Fever is also great. Really, every Tayler bottoming scene is iconic. I'm pleased 100% of the time and actually prefer him bottoming.

2. Jay Tee - Action (with Jkab Ethan Dale) and all of his scenes as Elder Edwards for Missionary Boys. (He has the best orgasms in porn; he's so underrated). I also prefer Jay bottoming, but he's just as good a top as well.

3. Blake Mitchell is another one - My go-to is his scenes with Joey Mills. But his best Joey scene is the 31 minute one where Joey is screaming with pleasure (any bottoming screaming with pleasure makes me cum). Another go-to is Blake and DancesWithLeos (I forgot his stage name, sorry!) kinky 17 minute OF scene where Blake yelled at him (I forget which one it was). Very, very hot!! Blake is at his best when he has kinky sex! He's one of my favorite doms.
