it is better to use PSR 970 or Tyros 4 it seems 970 has upgraded effects and prob little better sound pros but key bed and input channels XLR mic input keeps me in Tyros 4 it is my back up unit but keep hearing about 970 peeks my intrest

I wish they put a mic XLR and a guitar input on the 970

any thoughts ???
