Will they fill the role of what most 1911's are used for...? Yes under most situations , they will.
I have 3 non-colt 1911's. A Cimarron (German/Walther), a Turkish-made (name escapes me), and an AMT Hardballer. All three shoot just fine and are fine looking examples of the 1911 format.
I also have a Colt/Walther 1911 in .22lr. It too fills my hand and feels good like a 1911 should.
None of the above could hold a candle to the feel and beauty of a Smith "E" Series 1911 that I bought for a neighbor at a recent auction. It was freakin, beautiful...but it cost him $1200 and thats more than I feel like I can put into a pistol.
Take a look at quality (and cost)
American Tactical Imports 1911's are made by Shooters Arms manufacturing in the Phillipines. They are very much like Rock Island Armory's products. For anywhere from $365 to $500 you can get a 1911 in just about any configuration that'll more than likely shoot better than you can! They're reliable, extremely accurate, precicely manufactured 1911's that are more than worth the money you'll spend. You might find that they are machined with tighter tolerances than some of the higher end custom 1911's out there. I have every model of Rock Island Armory's 1911 lineup (also a Phillipine brand) and three ATI 1911's as well and never had a single problem with any one of them, the Phillipine's can make one fine functioning 1911, that much I can vouch for! Outstanding quality & accuracy for a fraction of the price of many popular "name brand" 1911's.
If it was me, I would get a Rock Island before an ATI. Secondly, I would shy away from a 3" 1911 of any brand. They've gotten better over the years, but reliability issues were and still are common. Find a full size or a commander and you'll be much happier. Just my 2 cents worth.
Not sure why anyone would want a Commander. The only difference is 3/4" of barrel length, and that's not much. The original lightweight Commander, now, that's a different story.
To answer the original question, I have a RIA 1911 Tactical made in the Phillipines, and if the ATI is even close, I'd say go for it. I like my Rock so much I sold my Kimber, if that tells you anything.
As I recall, the Rock was $450.00 or so, out the door.
