OK...my answer is going to be unpopular, based upon what everyone else has said. But hear me out before you flame me too badly.
Without question or reservation, I like #2, hands down.
Indeed, I find the argument against #2 because 'it looks like a Bentley' to be curious at best. Primarily because I have never seen any Bentley, regardless of model or vintage, with a grille even similar to this design. And I have seen a lot of Bentleys. It is similar to a couple of vintage Brits I can think of....but no Bentley in sight.
Number 1 is an E&G grille and, although it looks pretty good and I am sure it is nice enough, I have two problems with the E&G grills. First, they are becoming common and nearly generic. One of the reasons someone would want to do a mod such as this is in order to personalize their car. Adding the same grill that everybody and their brother is bolting on says 'hey look at me....I'm just as dull and boring as everyone else and I have absolutely nothing special about me.' Kind of like Chyslers' dim-witted decision to sell those anemic $23k versions of the 300 in the first place....with it, you can say 'Me too!'. But that is about all you'll say.
Second, E&G has got to get away from that cheap looking wing and medallion logo on their grills. They want to put a Chrysler and Wing logo on it...but can't because of fear of copyright infringement lawsuits. Going this route just cheapens the look. If you can't do something right....don't do it at all. Just leave the space blank and let us put true Wing and Medallions (purchased from Chrysler) on if we want them. Myself, I like the OEM Wing and Logo and would want to have the real deal instead of someone's cheap wannabe imitation.
Number 3 seems interesting enough.....but the picture is not detailed enough to tell exactly what it does look like. Perhaps, with a better pic I might change my mind on all of this. But, based solely upon the pictures given, #2 seems to have a much greater build quality. Better build even than #1. And....it is indeed a unique design. I have not seen another aftermarket design like it.
In fact, you've got me considering one for myself. I was seriously thinking about a mesh grille because none of the billet grills I'd seen have spoken to me. But, now I'm rethinking things.
