I consider the Smith's and Springfields the way to go when it comes to better quality production 1911's. I have one of the commander sized scandium models in a smith and 3 different springfields. All have been totally reliable to date, though the smith is newer and doesn't have tons of rounds through it yet, and only hardball so far. I sort of consider it a six of one/half dozen of another proposition when it comes to choosing say the basic 5" blued steel Smith or the park'd springfield loaded, say, which are comparably priced. Many of the differences are subjective/personal preference. The SA comes with an ambi safety and night sights, if those would be something you want, as well as front slide serrations. Personally, I'd lean more to the smith on these factors. The smith probably has the nicer finished slide. OTOH my smith probably has the most poorly crowned barrel I have ever seen. It doesn't seem to affect accuracy though, surprisingly, but is still somewhat disappointing. The Smiths also, like most other brands, actually, tend to have the somewhat mushy thumb safeties, whereas all my Springfield's have a nice, positive, not too heavy/not too light click on and off thumb safety. Af far as accuracy--My Loaded is more accurate than my Smith, but the smith is probably more accurate than my milspec or 4" lightweight model, though I somewhat suspect the poorer sights to be a factor with the milspec. The Smith sights are nice and show up well. As mentioned, reliability hasn't been a factor with any of them--no failures from the lot.
If the Smith is the way you are leaning, go for it and you should be happy--you see wayyyy more folks happy with theirs than not on most forums. As an alternative or if you're shopping around, the Springfields are very good IMO as well.
My only warning...like the potato chip commercial, no one can have just one 1911...you get one...then you want another...and another...
