>>8239011Hachiroku24 (left) is a more "cartoon-y" and fun design, only fitting 2 minifigures at most (1 driver, 1 turret gunner) and has decent stability when it comes to strength of the build - the only part that kinda sucks is the front tires and the bar that goes above the driver's head, both of those are quite fragile.
BrichTechStudios' design is more of a "realistic" approach, as it's one of the only Lego Warthogs that's closest to the source material at the moment - it fits 3 minifigures (as well as a brick-built Elite depending on where you put it,) fitting 2 minifigures in the driver & passenger seats, as well as 1 minifigure in the turret position. The Elite is able to fit in the turret and passenger spots.
Personally, I would go with BrickTech's design as I'm one for realism; the build is extremely stable (close to Lego-quality) and also uses common parts outside of the olive green pieces - it also has working suspension, a turret that can spin 360°, and a detailed interior space.
I thought this comparison would help those who wanted to build a Lego Warthog and didn't know where to start!
If anyone wants BrickTech's instructions for the 3 Warthogs (Gauss, Transport and regular) and a Hornet, drop your email in a reply & I'll send the MEGA file - it also includes parts lists for each build that you can import into Bricklink for ease of purchase.
