The only problem I've found is that unlike most VPS providers, they don't seem to do gigabit speeds in their cheaper tiers. I'm content with the 100mbit offering (which is 200mbit if you sign up these days, I think) so that's not a problem for my use case.
If you only run very basic stuff (basically a raspberry pi in the cloud) then Oracle offers two VPS servers for free (not "free for a year", "free with a purchase", actually "free forever", which was a huge surprise to me). You get very little in terms of performance but for a website or small project that should be sufficient.
They have many locations and I used their VPS for a long while before I moved to colocation. Had no issues apart from when I accidentally deleted /etc/.
Quite attractive pricing and been an user for about 2+ yrs, never faced any issue so far, probably luck me?
