A few things to remember about the 1911.
Philosophy. Mr. Browning designed it and called for specific tolerances in every part. Colt faithfully produced its 1911s to those specifications and to a great extent still does.
Loose or tight. While any well built Bullseye pistol can prove that exceptional fitting equates to exceptional accuracy that was not what the 1911 was designed or built for. Many, including me, prefer the greatest amount of accuracy possible (within budget) and a well-fit pistol.
Price. Colts are made in the US, Springfield imports ALL of their 1911s from Brazil. The difference in price paid is accounted for in labor cost alone, BUT...
Parts. Colt uses (with few exceptions like the disconnector and MSH) first-rate materials in their 1911s. Comparable Springfields do not. Add that difference to price as well.
As a base pistol for a custom build either is fine and, when considering the several hundred in savings a Springfield could be considered a bargain since all but the frame and slide are generally pitched.
My current production XSE is not drum tight but is built to "Enhanced" tolerances that give it a more than acceptable fit and no rattle save the side-to-side knock of the beavertail grip safety (now replaced). If considering either manufacturer, prioritize wants and remember what it is you're paying for. Some don't mind cheaper parts and overseas labor, something that in this case bothers me. I can say it's personal that there are particular countries whose economy I choose not to support. I buy Colts, among others, and also support local markets by having them customized.
It's not blasphemy, it's simply a matter of individual choice.
