Cultivation friendly vegetable cultivars? "Jumper" leeks anyone?

We are exploring different vegetable cultivars for their weed competitiveness and tolerance to mechanical cultivation.

For example, this year we’re trying ‘Jumper’ which is marketed as upright and easier to cultivate Jumper Leeks

Anyone have experience with this or other cultivars of leeks that can tolerate flextine cultvation or hilling better than others?

Any specific cultivars of other crops where you’ve noticed benefits for cultivation?
