If bang for your buck is a concern, you might be interested in this offering from Hetzner: http://www.hetzner.de/en/hosting/produkte_rootserver/ex4s - you get double the RAM and a bit more disk space for a little bit less. I only have a month's worth of experience to talk about it, but other than the fact that it's in Germany (timezones) it's been great.
Yep, have used Hetzner servers too for some things and would use again, but for our customers being 90% in the US, and OVH offer a canadian location (and we may need some EU servers in the future).
