Answer 1

Google Maps v3 is the next iteration of the API and my initial reaction would be to suggest that you use it. However, v3 is still a Google Labs product and is not as mature as the v2 API.

The initial focus for v3 was optimized performance and user experience on mobile platforms and ,as a result, some of the v2 features haven't made it into the v3 library (this gap is getting smaller). However, the performance improvements that have been made in v3 are equally applicable on the desktop, so you are faced with a performance/feature set trade off.

If there is a specific feature that is in v2 and not v3 and you aren't developing for a mobile device (and it sounds like you aren't), then you may want to use v2 and migrate to v3 once your feature is available.

Answer 2

In addition to Cannonade's answer, note that the scroll wheel feature can be enabled and disabled in v3, and even polygon editing is possible:

• Google Maps v3 Samples: Polygon Edit

I couldn't find any reference for the Google Bar however.

Answer 3

I found the syntax of V3 is better and more consistant than V2.
