NuevaSync for me. I've been waiting for more people to chime in with their experience with Google Sync before deciding if I should switch.
I'll likely go with the first of the two that offers Push Gmail
What I like about NuevaSync is that they support multiple calendars including "Other Calendars" that are linked with read-only access. I read that google only supports the main calendar.
Also a Sprint Diamond users was reporting that it messed up his 700+ contacts reorganizing them from First Last to Last First, and where he had multiple email addresses it would jam some of them into a single email address like "address1@xxx.com ::
address2@xyz.com ::
address3@abc.com" all for 1 email address.

I am looking forward to more competition in this space which will hopefully speed up development and feature releases.
