I don't like the size of the I serifs on 3, they're too long.  Other than that, it looks good.  
2 seems a bit blocky, the uprights are very vertical and the o's a bit too round.  
So yeah, I guess either 4 or 1.  The main difference again seems to be the serifs on the I's, 4 doesn't have any.  It also has more relaxed widths, although I prefer the curved tails on the y's in 1 to the straight tails in 4.  
So I guess original flavor for me.  Looks more handwritten, really.
