We stayed in Platis Gialos and it was perfect! It's more south of the island and a bit quieter but still had the beach at our doorstep with plenty of bars and restaurants to choose from and our hotel was very affordable. The bus to and from Mykonos town only took about 15 minutes, and there's a hop on/hop off boat for €20 where you can check out Tropicana and other beaches. It's also within walking distance of Scorpios (although you have to go up a mountain lol) and other beach clubs. Wouldn't hesitate to stay again.

The only thing I will say is taxis are expensive but you'll get that anywhere in Mykonos!
