I had a 3-18 V6 for a short time 3-4 years ago. I don’t remember the glass having a “wow” factor better than anything else I’d tried at the time. Sold it cause I needed illumination and wanted Mil adjustments.

From what I’ve seen out of the V4 line in recent years, I’m not convinced that the V6 is $800-$1000 better unless Zeiss has updated/upgraded the V6 since my sample of one.
