If I actually ahd a choice between the two, I'd definitely pick Recon, I'm never an elite, so I wouldn't get the Honor Guard armor. I'd almost prefer not to have it because there's a chance I could get hacked for it. =/
Honour Guard. All the way, I could care less how noticeable I am, or how large my head target is. Recon Helmet is F.U.B.A.R. ugly. Plus, people will think I'm a noob for wearing Elite, then I eat them alive. OM NOM NOM NOM.
Honor guard would be sweet, but it kinda looks pretty goofy. As for recon, it looks kinda strange and I never really liked it. If I had recon though I'd probably where it just to show it off though. Other than just showing off, I wouldn't use it. I would just use my normal armor.
Honor Guard is so sweet so if i didn't have recon I would pick the Honor Guard even though I dislike the Elite Model.
Well, Recon aside, I've always been miffed that there isn't an elite counterpart to the Spartan "Scout" armor. If anything, they should either put honor guard armor in or some new and unique set of elite armor for those who do get all of the halo 3 achievements but prefer not to play spartans. Regardless, I would certainly prefer honor guard armor to recon armor.
