I've been following the heirloom thread, and thought it might be helpful to separate the hybrids to another thread, and report our experiences, taste tests, etc. here.
Lemon Cherry is a really pretty tomato, and large for a cherry. No cracking or other problems. But, just about totally tasteless for me. And, did not at all live up to its early (58 day) promise - it was in fact way behind my 60-65 day tomatoes.
Sun Sugar, on the other hand, is a clear winner. This is by far the sweetest cherry I've tried. Reliable, no cracking, and so sweet. It is a smallish cherry, but produces well. Good size to just pop into the mouth or serve whole in salads.
Edited to correct: I've grown both Sun Gold and Sun Sugar, and it is the Sun Sugar that is my all-time favorite. Sweeter than Sun Gold which also cracked for me.
