Suggestions for moving a few VPS servers?

[Lvosspart]

Hi guys,
We're looking to move our current VPS servers, I'm looking for a recommendation about a good (and stable) hosting provider.
4 of the VPSs run high-traffic websites with a pretty standard setup, bandwidth is not an issue, and specs are also standard - 12-16 vCPU and 16 GB RAM for each of them.

The most important criteria is good support, root access, and customization options - for example, running LiteSpeed instead of Apache.
I'm not looking to save a few dollars, so any price range is okay.

Thanks a lot!
