Any views here on Melon varieties?

This year I grew Ogen and Sweetheart which seem to be the two varietes most
recommended for a cold greenhouse. The books seem to suggest that
Sweetheart is hardier and easier, but my experience is the opposite. The
Ogen plants are healthier and the fruits perfectly developed, sweet and
juicy. The Sweetheart plants look yellow by comparison and some of the
fruits have split (which is apparently caused by over-watering) as a result
of which they need to be harvested a little early.

Based on this experience, next year it will be Ogens all the way, but I
would be interested in the experiences of others.
