The short answer

On the fast boat from Piraeus, Agistri is the closer of the two: 50 min against 1 h 10 min for Poros, a difference of about 20 minutes each way. On a short trip that gap is worth more than it looks, because it applies twice.

Agistri has the better swimming, 4 out of 5 against 3 for Poros. It also has more of them: 6 beaches covered here against 5.

For sights off the sand, Agistri is the richer of the two: 8 places and museums against 6 on Poros.

Poros is the cheaper base, around 60 euros a night against 80 on Agistri, roughly 33 percent more. Over a week that is about 140 euros of difference on the room alone.
