The short answer

On the fast boat from Piraeus, Poros is the closer of the two: 1 h 10 min against 1 h 45 min for Hydra, a difference of about 35 minutes each way. On a short trip that gap is worth more than it looks, because it applies twice.

Hydra does not allow visitor cars, so you arrive on foot and get around by water taxi, mule or your own legs. Poros does, and the ferry carries them.

Poros has the better swimming, 3 out of 5 against 2 for Hydra. It also has more of them: 5 beaches covered here against 4.

Poros is the cheaper base, around 60 euros a night against 130 on Hydra, roughly 117 percent more. Over a week that is about 490 euros of difference on the room alone.

Poros is the quieter of the two. Both fill up at summer weekends when Athens empties into the Saronic, but Hydra carries more visitors through the season.
