I do not know to much about the S&W 1911s so, I'm not going to give you any pros or cons. That would would be unfair on my part.
But, I know a far share about the SF 1911s. I own both of the 2 SF you posted in SS. I love them.
http://www.springfield-armory.com/images/pistols/PX9154LLarge.jpg That is the newest of the 2 for me and I happen to like it the most. Comes with Novak's low mount night-sights 2 mags ext. ext. . It does not come with the "ambidextrous safety" like the other ss link you posted, but, I had one added to mine, took no time at all, I took it to my gun smith.
I will say that with both gun companys you are a getting a very stable history, a company that is not going any where, a great warranty and they are also very very proven companys, I do not think you can go wrong either way.
Shot what you like, what feels good and most importantly what you trust.
