Ruggr, I'm kind of in the same boat with tomatoes. A disadvantage is that my climate isn't very suitable for a lot of the heirlooms. But, I've come a long way from thinking I should have ONLY the very best slicer I could find and ONE variety of cherry each year.
My experience with your list is right there in the middle: Tigerella, Prudens Purple, and Stupice. None will be in my garden this year (I shoulda, coulda, woulda found room for them . . . but there were too many other choices!
Tigerella is a great little early tomato. I bought it as Mr. Stripey from a guy in Calgary but it isn't the Mr. Stripey that is available thru some US seed companies. Wait for the green stripes to change to yellow - very nice!
Prudens Purple was one of the 1st heirlooms that I grew. I was so impressed! Big, beautiful fruit on a really robust vine. Still, it came right up against the 1st frost for ripening. They didn't have any trouble on my kitchen counter if they had to come into the house because of the cold.
Stupice is another nice early and really my choice has to be between it and Bloody Butcher. DW made up my mind for me by continuing to call Stupice, my "stupid" tomato. I could only nurse my hurt feelings so long -- and still harvest what was invariably slightly deformed fruit. Perhaps a different strain of Stupice would have been more attractive. On a positive note, she really doesn't like the flavor of either Stupice or BB! So, he who laughs last . .
I will grow a Kellogg's Breakfast this year but only 1 plant and only because a good gardening friend sent me the seeds and another friend claims it as his absolute favorite! I really don't think that it will ripen here but am willing to be pleasantly surprised!
I had Orange Minsk last year - now there was a tomato DW liked - so I want to phase it out . . .
. . . I mean, the darn HUGE plant only had 3 fruits!! Anyway, I've got Woodle's Orange and Dagma's Perfection that are new-to-me and I'm fairly optimistic about! I keep referring to "Perfection" as DW's orange tomato because the name is so inspiring.
I figure I've got her fooled for awhile yet - and, if it performs well I might come off looking real good.
