Well Whites are the closest. Finish is better on the vibergs but 200 plus difference in price. Whites have from what I've seen are considered more comfortable and a bit more heavy duty, but all that is subjective. That opinion comes from multiple testimony but obviously take it for what it's worth.
Also, I'd also take an Alden cordovan boot with the commando sole or Trickers cordovan with a Danite sole which are the same price as cxl vibergs.
