Couple way to look at it...
Id consider both the T206 and T205s as "Classic Sets" but I dont like them much nowadays because they are way to common overall.
I got over 50% complete on both sets when I first got into vintage 25+ years ago, but then got bored and sold them off within a year, they were way too easy. I liked the rarer stuff early on so seaked out the much tougher related or similar sets...
Some collectors like (to collect) cards that others dont have, or are very tough overall ie T204, T208, T209, T211, T212-1, T213-1, T213-3, T214, etc. But now these will cost a lot even in low grade..... back then cards from these other sets often sold for only slightly more than the common tobacco cards (T205, T206, T207).
Thats just me
