I used to grow them, but now I've 'graduated' to wanting to try more exotic varieties. They don't mature all that much sooner for me anyway, so I try different shapes, sizes and colors of tomatoes each year. I bought transplants of Yellow Pear and a red grape called Juliet at Lowe's today. On top of that I have seedlings coming along of my favorite Momotaro, and another cherry called 'Sugary'.
The last two (warmish) winters I've been able to keep my tomatoes bearing right through winter anyway, so the earliness became not so important.
