I'm looking for first hand knowledge of a supposedly rare tomato variety. I received a freebie commentary variety called "Best Of All."  Have you grown this mater? If so-- what results, in which zone?
PS-- Trying to thin numbers of experimental seeds. I already know the computerized description.

Can't say that I've ever heard of it. That wasn't helpful at all, was it...?

After consulting The Great God Google, I found this:

'Seattle's Best of All' is an heirloom variety generally ready for harvest 80 days after sowing. Indeterminate vines produce nonuniform medium-sized fruits all summer long. Especially popular in the Puget Sound region.Sep 20, 2016

goodloe---That was a freebie gift from Timeless Tomatoes. Ya get free delivery with 3 packs. I've always ordered 4 packs, and get a freebie. They generally try and match what they suspect you were shopping for. I was ordering heat/drought tolerant varieties. Thus they gave me a seed from India. Where tomatoes have to have those qualities. I like Timeless-- but I pay no attention to advertised claims. I'm thinking it is a India market variety. I'm hoping to get a taste review.

Bonnies Plants lists Seattle's Best of All as one of the plants they sale... and Rutgers describes it as a late season, regular leaf, round red tomato so that one is probably not be that rare. However there is a release by IARI New Delhi simply called Best of All and at least one person on Etsy is selling a variety called Sutton's Best of All...
It sounds like you got the Indian version but it is hard to find any information on it. It was released in 1975 by IARI New Delhi. I found sort of ad https://tomato118.weebly.com/best-of-all.html and a paper that said it was not resistant to Alternaria solani (early blight) or Cladosporium fulvum (tomato leaf mold) which could explain why it was replaced by other varieties in India.
