None of these banks is suitable for non-resident banking. Fees are high and interest rates on USD deposits lower than in Singapore. It is also difficult to do SWIFT transfers. So, from an economic standpoint it is nonsense to even consider Armenia or Georgia for banking.
However, since the OP picked the Caucasus with the intention to bank outside the EU, this purpose is better fulfilled in Armenia because Armenia has no ambitions to please Bruxelles.
.... which is a bank headquartered in an EU-jurisdiction.
I doubt the OP Iikes that idea.
