How to deal with online lag?

Hello,

I played about 1000 games of mkx and guilty gear online each, but after the first few months of both games I stopped because I was getting 1 or 2 bar players every single match for weeks. I have 60 mbps wired internet and I always have 4 bars so I know it's not me, I play on ps4. I sometimes watched streamers or videos of people playing and they always get 4 connection opponents.

I really want to practice more so I can attempt tournaments sometimes. I know people say play offline, but where I am there isn't any community or players as far as I know. I love online play but I need to find a solution for this issue, is xbox's connection that much better? I rarely hear any issues with them. For example I would go in mkx player match rooms and 9/10 players had 1 bar latency, same thing for guilty gear xrd.

Edit : As a side note I've never had any issues with mmo's rts or shooters, and I've played close to 15 000 games in moba's. I just hope there's a solution for fighting games because I really want to keep playing them.
