Jeff,
I have every tank Honour Bound made except the gold edition Sturmtiger, a First Legion armored car, literally hundreds of pieces of King & Country armor spanning the early wood, metal and resin offerings to the most recent polystone offerings, and most of the armored vehicles Figarti has produced to date. I compared the John Jenkins tanks to all of these, many of which were two to nearly three times the price of the JJD offerings, and in my opinion (and remember, this is opinion, which is subjective, and everyone is entitled to their own, which is no less valid than mine) the overall quality, detailing, weathering and accuracy of these JJD tanks are unmatched in the industry.
The weathering is amazing, its not painted on, it looks like they attached real dirt, grime and dust. The rust is painted on, but more realistically than any other I have seen.
There is interior detail within the turret, something I have only seen in the Honour Bound Gold Edition Sturmtiger at three times the price and the Figarti Tigers and M3 Grant/Lee, at more than twice the price.
The detail of the sculpting in the mixed media resin and metal format is the equal of the best Honour Bound, Figarti or First Legion offerings.
I would rank them overall the best in quality, and overall the best bargain.
