I use digital, but can't see any real, appreciable difference between the two. I also wouldn't trust or bother with using the bezel. Between the watch, and my computer/bottom timer I've got redundant info on my bottom time.
I just bought a new one on sale, but still have my trusty Casio digital. You can have it for free if you want. It already has a deluxe velcro divers band, and I can bring it to the DIR presentation or BTS for you. Let me know.....

PS- To finish answering your question, I look at the time on my watch when I hit bottom, and keep track of BT throughout the dive. This way if either device fails, I have a pretty accurate idea of how long I've been down.
If you don't like the idea of memorizing, you could use the stopwatch or write the time down in your wet notes.
