First, you get one of their "VM.Standard.A1.Flex" instances:

• Ampere A1 (arm64) processors (that's Neoverse-N1 cores)
• 24gb RAM
• Up to 200gb of block storage
• 1 ipv4

The bad:

• Oracle Cloud UI is subpar, even compared to their competitors' which aren't great themselves (AWS, Azure...)
• Instances may not be available for creation in your prefered region depending on when you're trying it. I choose a nearby region and it's worked fine for me.
• Depending on your luck, registering can be a hassle due to strong anti fraud checks which also impact legitimate users: UI is slow and unreliable, and the process may fail without a clear reason.
• You need to give a credit card number, although they won't charge you.
• We're talking about an ARM instance, this can be a problem if you want to run x86/amd64 specific software, though that's becoming less of an issue over time.

The good:

• Unusually powerful cpu, incredible ram amount, sizeable storage.
• Instance/network seem fairly reliable, no major problem since I've been using it.
• I've run heavy stuff such as Elasticsearch and Kubernetes on it, with success.

You can look at some benchmarks just after, but to sum up, I'd say that if you can pass their registration process and there are instances available, it's kind of a no-brainer.

Also check out their free databases, they are fast as hell (even Amazon is using those, because their own solution is to slow, lol).
