Manually crossing tomatoes

How do people feel about the different tomato leaves? Is there a specific benefit of potato leaf tomatoes? I have a bias towards them but don’t know why. Maybe it’s the Black Sea Man I have, which just looks so sturdy and the leaves look really strong and solar-efficient. I have a feeling I may also have read some benefit of the potato leaf types, but I can’t remember what.

I’m trying to cross Black Sea Man with wilds, because it seems so sturdy and such big and relatively early tomatoes, that people say have great flavour - I am yet to taste them. It seems like a great candidate to cross with wilds.
