The ARM VM provided by Oracle is actually quite powerful (definitely much more so than anything free by GCP or AWS). Since I have no point of reference for that processor, I have no idea if you're getting four real cores, but it at least feels so. Compiling large C projects is faster than doing it on my machine (although the target architecture is different, so the comparison is a bit pointless).
The two x86 VMs are puny and can only be used as VPN gateways, or for static site hosting, or something like that.
Not using any of that newfangled "serverless" nonsense, and do not plan to. For work projects we rely on colocation with properly self-provisioned and fully controlled servers. It would be silly to use free tiers since you get absolutely zero uptime guarantees.
