Schrock is the cheapest of the 3 you list. For a reason. But do you need Level 6 Cabinets if Level 4 will do the job? You may aspire to Level 8, but settle for 6. Same with aspiring to Level 6 and settling for a 4. What Level home do you own? What’s your percentile in the market? Realistically?

The limitations of lower priced and specified lines is the numbers of colors offered, the numbers of modifications offered, and what is considered “standard” construction vs “upgraded” construction. People create good looking kitchens all the time from some of the cheapest no features or color options cabinets around. Cheepchinesecrapola. Because they find a color that works for them, and they have a designer that can work within the limitations of the line, and and they don’t start upgrading the basic construction.

When you start throwing all kinds of “upgrades” onto a lower line, you might as well move to a line where those features are standard.

Decide what the lowest level is that you are willing to live with for 5 years. Buy those.

It sounds like you need the line that has the most durable door finish. I have no experience with either line. But your designer does, and should be able to steer you in the right direction.
