First, the tamiya is the best kit of wwII jeep. The italeri looks good and priceless.
About detail sets, i think there is a difference beetween Aber-eduard and verlinden-legend.
The first is photoetched set only, great quality, but without added resin part.
attention with compatibility, one are done for italeri, but i'm not sure.

And, if the price is not a problem, i advise you to bought the verlinden or legend productions kit, with a beautiful M2HB machine gun ! in the same set, there is photoetched part and resin part.
About the quality, it's the same.
If you need help, there is a lot of real jeep in france....
