My builder is giving me a choice of using Wellborn Select cabinets or Kith cabinets for my bathrooms, laundry and wet bar. Out kitchen cabinets will be custom by Mullet Cabinet,

i have heard of Wellborn and they seem to have a decent reputation but I am not familiar with Kith. The Wellborn cabinets are $1350 more. The builder said these are the same company but I actually don't think that is the case at all. i am trying to negotiate to get the Wellborn cabinets without the extra 1350 upcharge and am trying to understand the quality and construction differences between the two manufacturers.

Any experience with with of these two cabinet companies?
