I agree Marsha. Kellogg's Breakfast does so well I even wonder why anyone would bother with the KBX "improvement". What? You want something better than loads of 1-2+ pound perfect monster tomatoes that taste awesome and keep producing right up till frost?
But KBX is more uniform...almost tastes as good...almost gets as big.....almost produces as many fruit...for me "almost as good" is not as good......so for me I go for Kellogg's Breakfast.....but someone else might not get dependable production from Kellogg's and for them "almost as good" is better than a crop failure that produces nothing.
And here we find that even the hybrid super sauce has tremendous variation.
