I guess it's a personal preference... personally, I find changing him to be about the same whether he's in pants or footies.... DH and mom really prefer footies... becuase you have to take pants off... and if he pees on himself, you have both the bottom, the jacket/sweater, and the onsie to change...

I will say that for me, footies with a zipper seem easier than everything else... unzip, take legs out, re-diaper, stuff legs back in and zip back up.... all very fast.
