Since just posting in this thread now, I've bought a few classics over two months. Got Prime, Megatron, Hot Rod...err Rodimus (since they can't use 'hot rod' anymore lol), Starscream, Bumblebee, Grimlock, and Astrotrain.
Bumblebees gotta be the best version of him yet, he may not be a bug but he has a great head sculpt. I like the Grimlock too, but his legs are just slightly off to me as his lower legs take up too much of his entire leg length. Astrotrain doesn't quite feel like the old one, but I think I like him better as it's actual transformations and not just flipping mini panels over. Starscream is prob the best of the lot, Prime's great but that see thru blue they put in to make his eyes glow with light is too dark and his eyes seem to always stay a really dark blue.
As for Megatron I went ahead and removed the pin connecting the 'wings' to the rest of the body lol. I did it with no visible damage to the figure, and he can still transform as the wings clip together and hold on fine. You can't tell the difference when he's transformed, and when he's in robot mode he doesn't have the annoying green glowing wings. Only thing I suggest tho is take your time if you try to remove the pin, hairdryer+hammer and nail, and just do it slowly or it could ruin it.
I'm liking the look of that Ultra Magnus vs. Skywarp two pack, but closest Target is 30 miles away and not sure when it's coming out. Personally I wish they'd finish up the Dinobots, and make a triple changer Springer, and a Kup.
