That's irrelevant, actually. With BES there's no need to sync using OWA or DM. AFAIK, OWA is only of use with BIS and that's just for email forwarding. Anyway, with BES you sync OTA (wirelessly) via BES though you can choose to sync via DM if you want or need to.
In a BES/Exchange setting OWA just gives you an interface to your Exchange account from any web-connected PC. It's something that people rarely mention as a benefit of BES/Exchange but I use OWA all the time except when I'm on one of my home machines with a full blown copy of Outlook installed and configured to connect to my hosted Exchange account.
If you have several other users on the same hosting account you can, of course, take advantage of other Exchange features like meeting scheduling, meeting requests, shared folders, etc... My wife and I actually use meeting requests a LOT to stick things on each other's calendars.

There are actually quite a few good BES hosting providers out there.
