You are better of starting on a new server if you care for PVP. Hopefully, you know what to do in terms of keeping up with power as a lot of people just jump to do plot instance only and end up being food for people in PVP.

Another point to bring up is that there is an issue with new servers on NY region. It appears that with the Brazilian server closing not to long ago, they migrated over and seems to have a lot of players whaling to scale that they match or greater in power with players on older servers. So, if you play on NY, there's a chance you might play on a server that was even worse off when you last played.
