I'm glad you found the articles helpful.
Looking at the two you have listed, I don't think you could go wrong either way.
Both have great warranties, both are equipped about the same.
Buds has the S&W listed @ $810 delivered, the Springfield Loaded Target is not listed there, but it should also be within the price range. You might want to give CDNN a call and see what they price the Springer at, I know I priced a Loaded Target a while back and the price was very good, I'll see if I can find the quoted price from a few months ago, it will probably be a little higher now, but should give you a good estimate.
I would take the Springfield as I don't really care for the two tone appearance of the S&W, but that's a personal decision.
Both are going to have the full guide rod, which I would remove as it gives no real advantage.
Some would take either model due to the different extractors, the Smith has the external (Kimber had issues with this, but it seems S&W did it right) and the Springer has the original internal extractor.
On the Springer I would take out the locking mainspring housing, I don't think the S&W 1911s have an internal lock, but I could be wrong.
Another small detail that I find annoying with the S&W guns is that if they don't have the magazine disconnect, they have the guns marked "Gun can fire with magazine removed" or some such text, I just think it looks tacky.
Both guns are great, this one all comes down to personal preference.
*ETA* Back in March CDNN had the Loaded Target for under $800.
