Due to historical reasons, physicists who do not have a strong preference for a particular interpretation default to the Copenhagen one, despite some of its pseudo-mythical outgrowth - which you can just ignore if you are in the 'shut up and calculate' camp.
It doesn't help that every other interpretation (at least those I know of) contains some flaw or quirk I find unacceptable as well, which would leave me with the statistical one (and perhaps consistent histories), basically not explaining anything at all.
The ones I like best are Cramer's transactional one and de Broglie's double solution, with the caveat that these should be backed by a mathematicaltheoretical framework beyond quantum mechanics, but aren't.
Personally, I'm one of these cranks who think that we should be able to back quantum mechanics with a realist theory (but a superdeterministic one): Start from de Broglie's double solution, throw in the geon model of elementary particles and ER=EPR and you're good to go.
