It depends very much on what it is you try to achieve I think! For instant for my testing purpose Breder and WorldCore is the best. For my business I have had good experience with for instant Piraeus, Hellenic Bank and finally AfrAsia Bank Ltd!
Breder works fine with my personal account.. it was actually easy to get the account after documents were provided. I have not made any transfer yet since I'm negotiating with them about a business deal, waiting for them to get back.
They confirmed yes.. but as mentioned I have no money there yet because of some ongoing negotitation. Do you have had any problems with outgoing transactions?
For Mauritius, there are other options other than Standard Bank. Mauritius Commercial Bank (MCB) is excellent and very responsive. At the very least, there should be an "other" option in the list above as there are many members here who do not use any of the above but other banks.
Also, can you open remotely at Piraeus ? two different cases 1/ individual non sepa non american. 1/for a company EU based.
Everything clean, legitimate online business, all sorts of documents can be provided.
