Recently I ran across something that mentioned growing Tomatoes from seed vs growing from a clone.

The Tomatoes grown from seed will send down a tap root up to 5 feet deep.

Clones do not make or send down a tap root but make a lot of shallow roots.

Has anyone experienced this?

I'm not yet aware of seeds versus clones comparisons, but I am aware of tomatoes grown from seeds versus transplant comparisons. The general consensus on this has mostly been that tomatoes grown from seed develop taproots and survive better. We have generally also observed that when trees from seeds versus transplants that the trees grown from seeds have taproots and usually do better, too.
