I used to do a lot of doweling but then got a hollow chisel setup and went to mortice and tenons. I think the tenons are a little stronger and I find them easier to fit. Multiple dowel holes were hard to keep aligned compared to a tenon. (I didn't have a dowel max.) With a tenon there are extra steps that can be taken to reinforce the joint such as wedging the end of the tenon or pegging the tenon with a cross dowel.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
