DS is pretty even between PS4 and X360. I haven't played the Switch version, but the extra lag there knocks it out of contention (this is why I don't buy Switch STGs in general).
DSMBL is better on PS4 than the X360, due to the slightly more accurate slowdown replication.
DSII is still best on the X360. The PS4 version is rather poor. Outside of the lag issue the Switch port is apparently pretty close to the X360 version, but not perfect.
Basically, if I want to play DS or DSMBL I'll probably go with my PS4 copy (though I am happy playing the X360 ports as well). If I want to play DSII I'll play my X360 copy.
