The 84 Cell Plant Propagation tray is the best all-round plug tray size, in fact, it's the one we use ourselves in our nurseries.

The trays are the perfect size for most 4 week old plugs after which time they need to be planted out or potted on. These trays work great in conjunction with a propagator.
