I print nearly exclusively in ABS. It prints cleaner and slightly quicker than PETG and my end result is smoother IMO. You also don't have to deal with the transparency. Though I do have an enclosed printer which makes a lot of the typical hassle of ABS printing go away.
I do have some OG prints done in PLA that are sitting in my tanks that have held up with no noticeable degradation over approximately 18 months, but its hard to say whether or not that is typical.
