I was never a Gen 1 fan for the first year. Thought the trucks looked like an f150 got beat with an ugly stick. After a while it grew on me, especially after seeing them in person, enough where by 2011 it got me to the point where I had to have one and ended up getting a 2012.
The Gen 2 I absolutely love it. Especially the front end and lighting. Less weight to boot, improved shocks, and all the other improvements they make yearly. The main thing I'm not huge on is the smaller fender vents and ditching SVT for FP name branding, but that's minor. Overall I see it as improvements.
As far as the elephant in the room, the V6, well I purposely didn't order a 2011 because I was hoping in 2012 they'd offer the 3.5 EB as an optional engine. When that didn't happen I just got a 2012 anyway, but I've always wanted an EB raptor. We ended up getting a 2013 Explorer Sport with the 3.5 EB TT engine and I love that thing. And while yes a V6 exhaust note isn't as iconic as V8, I tell you it's not that bad, and the turbo whirl in the exhaust definitely regains some points in the cool factor. I'm a forced induction junkie though, so I can tolerate a V6 exhaust note so long as there's turbo whirl in it lol.
My 2012 will be paid off in 2018, so more than likely I'll be getting a 2019/3rd model year of the Gen 2, so not worried about any initial bugs with the 10 speed or new 3.5 since hopefully they'll be worked out by then if there are any.
