A slight quibble, and I'm sure the OP will put us right, but from the nature of his post I believe he was using the term "Greek Islands" as a generic reference to Greek waters.
Anyway, the Saronic and Inland Ionian are both suitable for winter cruising in settled weather, with enough bolt holes for unsettled periods. And even though a lot of facilities close down, both areas have centres which remain fully alive all winter. If you count Lefkas as an island! No argument about Poros I think . . .
On average we used to get only 3 very bad days weather, i.e. force10+ in the Poros area a winter. lots of rain though The rest of the time very manageable
