I much prefer the T-206 over Old Judges. However, if you truly love the 19th century era most of all, collect the OJs. I imagine you'd be happier with more than a few cards, but if the few cards you would have represent the time period you favor the most, that's where you'll be more fulfilled.
Unfortunately, the cost is exorbitant no matter which of these you choose.
OR, identify what cards attract your eye the most from both sets---get a little of both. No law says you have to have just one. (card company issue, that is!!)
