Guitar Choice (Fender Stratocaster versus Gibson SG 61' reissue)

The Time has finally come for me to buy a new electric guitar! Yes an expensive one!
Problem is i don't know what guitar.
I have busted my ass for a year now and now i am on a dilemma.
Should it be the Gibson SG? (61' reissue model) or a Fender Stratocaster?(American made...the deluxe model)
I play lots of music (mostly focusing on hard rock) and i love both guitars.
Problem with the SG is that i won't be able to install a tremolo but it's not like it's the most vital thing for me.
These "mama's" are so different!This SG model i gotta say has the thinnest neck Gibson has to offer.

And then there is alway the Stratocaster...
