Personal experience with DO: I've been a happy DO customer for the past [7 years](1). Linux VM [uptime](2) record has been amazing for personal use case.
This week I migrate the droplet hosting my personal website (5/m) from DigitalOcean to Amazon Lightsail (3.5/m plan) this week. Trigger being Ubuntu LTS upgrade to 20.04 again failed to boot on first few attempts again (wasted quite sometime chroot trying to fix to no avail without access to the hypervisor - IaaS...), mainly because of the way DO's flavour of KVM (hypervisor) works (I am not the only one), my other VPS (e.g. 123Systems - KVM) worked well and never had the same problem, let alone Xen powered VMs (EC2, self-hosted XenServer, etc. - I know hypervisor well because I've worked for XenSource/Citrix on XenServer for several years).
Customer (technical) support quality has dropped over the last few years, I can tell the difference by comparing the last 2 support tickets, I don't want to guess the root cause, sigh...
Finally I have had enough (4th time down with upgrade), it's time to move on to something better without paying more, migration is made easy due to the way workloads are deployed (most containerized, thanks to Docker/Docker Compose). With Lightsail, in addition to the AWS name/brand, has the advantage to move the Lightsail VMs into AWS EC2 instances so as to leverage full-fledged AWS infra (e.g. VPC, etc.) seamlessly.
Over the years, low end VPS competition has becoming much tougher (DO, Linode, Vultr, Amazon Lightsail late to the game but powerful strike, etc.) DO has lots its key competencies for bang for the buck, without offering 2.5~3.5/m plan on par with competitors.
Last but not least, I'll definitely consider DO as an option when Cloud Infrastructure is need, still ;-)
BTW: On Oracle, my Oracle Cloud free tier trial ended miserably, 2 weeks after provisioning the VMs, Cockpit (I run it on my home NAS - managing/monitoring a small group of cloud VPS using the web UI) reported connection failed, only to find that my account has been terminated without any warning or notification along with my 2 free VMs based in Phoenix, lucky that I didn't actually put any workload on it (left them running only - feeling something's gonna happen...), contacted support and was told account deleted, no reason, redirected me to customer support (my oracle support, I couldn't figure out how that works, so give up...). I still don't understand how Oracle Cloud login works...
