Mexico Midget is SO prolific and dries well. If you are into hybrids, I love the taste of Sun Gold. We tried Reisentraube last year and did not care for it. I am excited to try White Currant this year. I have yet to find an heirloom cherry tomato whose taste I am wild about but I'll keep trying!
Yeah, I'm trying to stick with heirloom/OP stuff so I can save seed from 'em. Secure food source and all that jazz.
But honestly, I haven't had cherry/grape tomatoes in a few years, so as long as I find something that's not super acidic/tart, I'm good. I have a bit of a sweet tooth. And I figure, worse comes to worse, I'll zap 'em in the microwave and run 'em through the squeezo for tomato sauce if I can't keep up.

Can't recommend this outright because I haven't grown them yet, but I just bought some Blondkopfchen tomato seeds from Seed Savers exchange.
The description says they have "excellent,sweet taste" and "enormous yields".
Ok, I withdraw my Sungold vote because I just saw this. Someone in the seed swap thread posted this link to free OP tomatoes, and I see multiple cherries. I can't vouch for most of them, but hey, they're free!
