Oracle Cloud's prices are the same across all regions, which is nice. They do not offer any reserved discounts, but do offer a 50% discount for preemptible (spot) instances. One complication is that their prices are per "Oracle CPU" (OCPU). This seemed to make sense originally, as it corresponded to physical cores - the A1 instances had 1 OCPU per core, so 1 OCPU = 1 vCPU, while SMT x86 had 1 OCPU = 2 vCPU (threads). But then, possibly thinking that their users are getting comfortable with it, they threw a wrench by making 1 OCPU for newer (still non-SMT) ARM types A2 and A4 be equal to 2 vCPU / 2 full Cores. I can't think of a reason for this other than to confuse their customers.
In practice, it behaves like an OEM lock justified in regulatory terms. The same XMM7560 family has shown up across multiple OEM laptops, with different vendors using different unlock material. The radio is identical across hosts; what changes is the OEM-controlled signature that gates its use.
