2 bed 2 bath ea unit Duplex or 1bed 1 bath Quadplex?

[Steven Fontes]

I have been looking at multifamily a lot and ran into a 4plex property with a goos cash flow statement that was a slam dunk it seemed, but each unit was 1bed 1bath. Is it hard to find long-term tenant for this? Or am I better off 2 bed 1 bath duplex? The duplex seemed harder to positive cash flow off of than the 4plex
