To a degree, 1911s are unreliable. However, it's complete BS to say all 1911s are unreliable. My carry gun, a Wilson CQB passed my torture test. After intial break in (500 rounds), I fired it 1000 times without cleaning to see if it would jam. It passed with flying colors. It finally jammed around 1200 rounds WITHOUT cleaning.
I fired it from all different positions, limpwristing and all. It still functioned flawlessly. If that's not reliable, than I don't know what is. However, the 3 Kimbers I used to own were not reliable. Neither is the Les Baer I own and a Springfield V10. My Ed Brown, Colt 1991, and Wilson Sentinel are also reliable.
To answer your question, I prefer:
1. the single action of a 1911
2. Steel
3. Single Stack
4. bazillion parts for customization
5. I can shoot just about any reload.. lead and all
Like I stated before, it's personal preference. I like my G30 but prefer my 1911s.
To further elaborate on your question, yes I have personal experience that dictates my choice. I do quite well in ISPC and IDPA matches with a 1911. Although I never tried a Glock in competition, I really do not think it would do nearly as well. Why is it a majority of world class ISPC and IDPA shooters use 1911s?
