Question

Google Maps API v2 vs Google Maps API v3?

why Google create a new one?

what are the prons and cons?

which one to use?

Answer 1

Google Maps v3 is very slow when it comes to subclassing overlay classes. Most of the time when you have some custom overlays on your map it will start to LAG which means it is unusable in most cases.

Version 2 is much, much, much FASTER for REAL PURPOSES.

Unfortunatelly it is not supported anymore :(

Answer 2

V2 is deprecated. Google will continue to support V2, (fix eventual bugs), for at least 3 years, but no new features will be added to it. V3 is the current version.

Why create a new one? Because V2 was made before smartphones became a common everyday device. V3 is much lighter and faster, and it is specifically oriented towards mobile devices, though it performs fine on PC as well, of course.

google maps api v3 is NOT a replacement of v2. It's missing many features of v2, so you can quickly get dissapointed. I think this post explains it the best:

and also, if you need to manage a lot of markers, according to this post v2 is the way:
