SESD | I don't have either, but different systems by design. Exapta system ties the whole down pressure system together, but I believe can run automatically. The benefit is even pressure among all openers whatever the depth, as opposed to losing contact on some and spring compressed and too high of pressure on others. Probably considerably cheaper than PP.
PP would or could be individual row downforce IIRC. | |
