How about a head to head competition between you and I.
We put side to side your best " digitally printed " picture against one of my " fiber base gallery quality " that I spent 3 hours to print in my darkroom !!!!
At high noon at the OK Corral?
Are we talking my DSLR against your 35mm or are you going to go all large format on me?
Nine out of 10 people attending a gallery show wouldn't be able to tell the difference between a print from a DSLR and a print from 35mm film.
Then as soon as we're done with this test let's do another. We'll each shoot the same subject, you with film, me with digital, and we'll see who can get a photo to a publisher faster.
And this is my point. No one camera will do everything better than anything else. They're just tools. Own them all and use the best available for the job if you can. If not, then own the best, jack-of-all-trades, tool that you can.
I'm curious, why do you HAVE to shoot digital UW? I switched to digital when my boss handed me digital cameras and took away my film cameras. I continued to shoot film with my personal cameras on special projects until 2004 when I realized it just wasn't worth it. I finally sold the last of them.
I believe the OP's question about durability has been answered. Any camera is going to suffer if flooded. But digital, or specifically all electronic cameras, will suffer a worse fate if flooded. But I'll put my EOS 1D MKIIn's up against ANY camera in a rainstorm. They have over 70 o-rings and gaskets installed. They can so much rain I rarely bother with my rain covers anymore.
