The choice between tubeless and tubes is literally finding what works better for you, gradually loosing all your air in 24 hours or a risk of a sudden loss of pressure when you least expect it.
I don't think tubeless typically has a problem with air retention. The easiest thing the OP can do is to fill up his one tire that has the tubeless setup and see for himself if it leaks air.
In any event I think the tube-tubeless debate is over in the case of MTB's. Tubeless is pretty much standard now. The debate is still ongoing with road bikes.
