Is it me or is there a ton of lag online on games other than MvC2?

Switch user playing online ranked, and I'm noticing that whenever I'm playing MvC2, it runs smooth as butter, but MSHvSF and sometimes MvC1 suffer from lag.

XvSF runs fine but I don't usually play it that much, and I tend to stay away from CotA and MSH, but does anyone else experience this or is it just me?
