2 HOB filters (aquaclear 70&110), or a Rena XP4 canister filter for my 90 gal tank ?

xP4 period. I have two xP3s on mine. Best "fish" decision I've made yet. I've posted this pic a million times, but I like to show off when somethings done right. IMO, two smaller canisters IE xP3s do a better job than 1 large.
