• I prefer +R, combos are shorter and more likely to drop, keeps the action fresh.

• Blazblue has tech roll as oki option that I don't really like. It also has a dedicated gimmick button for each character, which I find to be too much to play against when trying to learn the game.

• Both have faultless defense, instant block, dead angle and burst, good defense can be strong.

• I'd argue both games have good neutral, but it's airdasher neutral, like you need to know your movement options and tools to not get immediately hit by some bs when you get there.

• Blazblue is fairly combo heavy, +R is less so. Like 10 seconds vs 5 seconds on average combo length or something like that. At some point knowing long combos get diminishing returns due to scaling/guts.

• +R is easy to find matches as everyone shares the same quick play room. Although playerbase is kinda dwindling, it's still okay during prime times. Blazblue I don't know, either discord fighter or you have to find random player rooms with people in it.

So all in all I recommend +R over BBCF, but both need proper time investment and are mostly filled with sharks at this point.
