That would highly depend on the 1911...one made to actual drawing spec shooting ammo for which designed from a magazine with feed lips to spec is a mighty reliable machine, and the military tested the 1911 numerous times in its service life and nothing ever came close that they ever tested as a replacement. The problems today are sloppy guns and magazines modified to feed hollowpoints. On my 2016 Colt, which was suprisingly perfect for Colts of the last 25yrs, it easily puts two magazines into 2.5"/25yds, and I have tried and failed to induce jams annually since purchase....ditto in all respects to my 100% GI parts WWII gun...it's kinda hard to fault that manner of accuracy and reliability...will not claim any manner of superiority in terminal ballistics compared to 9mm with modern reliable hollowpoints at nearly magnum handgun velocity which starts at 1200fps, but will point out the .45 has over 60% more frontal area without any expansion at all, upon.which expansion the 9mm must depend to work, and the .45ACP duplicates the most common military .45Colt loads used where nobody ever accused the .45Colt of being underpowered against anyone. If you have a properly made 1911 it lives up to the rep...if you have a crap "1911" made to whatever spec and materials feasible to a modern company, or a shot to pieces military rattletrap with a 50-100yr old worn frame and maybe original slide, all bets are off.Over rated or over priced? Personally I think it's a firearm that does not perform well or unsafe, so I'd say the Sig 320 just because there are many sig fanboys. I'd say in spite of the fact I like them, 1911's in .45 ACP are very over rated. The .45 ACP has a minimal advantage over 9 mm + P rounds or .357 Magnum, the 1911 is SA only, has a relatively small magazine capacity and is not as accurate as many pistols out of the box. People spend $100's upgrading them or have gunsmithing done. The 2011's do resolve many issues but I have yet to fire one. I do like 1911's, just do not think they are as great as the legends suggest.
