In terms of reliability, basically never down, they just recently had an IP change, which was really the only downtime (apart from a user error on my side) I've every had with them.
Pricing is great. (literally nothing to add, price is just great)
While their support is a bit slow, you usually get a response the same day if not the next, during holidays it can take a bit longer. They are always trying their best and very friendly. I had an issue where something broke the bootloader and they were eager to help with mounting a rescue ISO to the VM. (It didn't work, but i was able to "sanboot" via iPXE to an Ubuntu live ISO and repaired things from there). It was during Christmas so I wouldn't call it exactly their fault for being slow.
Their customer UI is some off-the-shelf thing but works well.
I had/have an issue with upload speed sometimes being very slow but their support was always helpful with whatever weirdness was going on. Moins
