I agree, any way ya shake it, this will be different, in a good way. But, it’s nothing I can’t handle.

I frequently get the opportunity to drive a 2015 Camaro SS 6-speed car. It has a 3.01 first with a 3.45 rear gear. That math comes out to a 10.38 effective first gear. Of course, it also has traction control, and I believe a 315 tire in the back… but point is, I can adjust, and probably avoid the inadvertent burnouts. 😎

I may consider the 3.55 rear gear with the close ratio… still a good first gear ratio (10.18) and (of course) slightly lower cruising rpm’s (60mph = 1,830 / 75mph = 2288). Although, for whatever reason, that’s the least voted for option in the poll… if I trust the poll, the “best” option would be the wide ratio trans with the 3.31 rear gear. Hmmm

I didn't even look at the poll, I just give my experiences with the the options you posted and why. As I mentioned, I use the 2.87 with 3.55's in one of the cars, with a .64 5th and it's a pleasure to drive. No reason it wouldn't be. Nice easy cruising on the interstates for the long trips. Every one I've ever swapped in I hear the same thing, "best money I've ever spent on the car" or "don't know why I didn't do this sooner" etc..... You'll be happy with either option.
The most likely reason your poll shows the 3.27 as a favorite is simply because most people on this forum don't have much rear gear in their cars, and the simple answer is they don't want to bother changing rear gears, it's expensive to do it right, takes special tools, and most can't do it themselves anyway and would have to pay a shop, so rather than dig into a rearend change, they opt for a steep 1st gear to basically avoid that deal. It's an extremely small sample rate on the forum here that really won't represent the vast majority.
