i'm probably an outlier, but i kinda really like the plastic shimano pf92 in my current bike (24mm crank). better than threaded, even. it's cheap, really light, super fast & easy to install (tappy tap tap with the BFH, no special tools required, no threads to worry about), and has been long lasting & noise free. plus, it's not going to seize in an aluminum frame. plastic, it's the future!
that said, if you're using a 30mm spindle, the direct fit bearing into bb shell detail (like the pf 92 enduro & hope) does seem to make good sense. pressing a bearing into an aluminum shell that has to be pressed (or threaded) into yet another aluminum shell (BB) seems a fairly inelegant solution.
also - if said enduro & hope pf's have solid reliability it kinda leads one to question the reasoning behind the DUB system.
