Main platform for Super Turbo Online in 2018/2019?


Hello ladies and gentlemen, I was wondering in what platform are most people playing on in these days. I plan to play ST at Combo Breaker 2019 and wanted to take it a bit more serious than just playing at the event aka train for it. GGPO, Fightcade, or new Anniversary collection on PS4? Would prefer PC but in this case looking for the largest player base to get games in. Whether is fightcade,ggpo, or the Street Fighter 30th Anniversary Collection on any platform. Don’t really care just looking to get some good games in and train.
