RunAbove 'Sandbox' instances overcommit RAM and provide no SLA. Sure, you can't beat the price, but if I wasn't interested in a SLA then I'd rather pay $10 and get a Kimsufi.
On the other hand, I never had an issue with my OVH 2$ (now 5$) server, and I run an Apache with worpress, an IRC bouncer for a handful of users, a mumble, a teamspeak and a minecraft server on it. Less than 100% CPU and RAM utilization.
OVH isn’t cheap because they don’t deliver the performance you ask for, OVH is cheap because they really don’t provide anything else in the free tier, no backups, no additional IPs, no guarantueed uptime.
