I can still remember when the Early Girl was a new introduction and featured on the cover of the Burpee catalog. I was struggling in an even more challenging tomato-growing climate than what I've got to contend with now. I was several hundred feet higher during those years.
It was difficult to resist but I can usually discount something "new & improved" for a few years

. What it came down to for me at that time was just growing Sub-arctics . . . thinking about going back to that variety kind of brings on a wave of depression

.
For years & years now, I've grown a few Early Girls. I have a neighbor who won't grow anything else. I can completely understand his loyalty; he's always been successful with them.
Various cherries are earlier in my garden than the Girls. That didn't used to be true, however. The only cherry that I knew about was Large Red Cherry and it couldn't beat Early Girls. But, I wouldn't want to give up the cherries that I have now. Aaand, there are a few heirlooms that are early enuf, that I can grow. Big Beef is right in there and has been almost since its introduction. Still, I'm happy to have several Early Girls and the flavor suits my tastes, as well
