DigitalOcean. Seriously. They have been around a long long time and built a lot of the core infrastructure you rely on every day (e.g. Ceph).
I have read plenty of snark about them on HN, but I found their product incredibly useful, well-designed, and easy to work with. If I was building a new startup from scratch, I'd definitely be giving them a look.
I'm sure there are plenty of the like 1,000 AWS products that DO has no viable competitor for, but for what they do offer, they're great.
I've used DigitalOcean for personal projects for over a decade, no major issues so I definitely recommend!
I've had nothing but good experiences with them and their docs and tutorials are excellent.
Yes, I use DO with Hatchbox. It is a perfect combo. Been using for more and more projects.
I;ve had my share of VPS & Managed DB outages at DO, so they are also not faultless.
