All of the Above
My pick was "other" because each of the three have been a major factor in at least one purchase, and ALL three in some. Never has any one been the single reason - looks or feel alone isn't a valid reason for me to buy a rifle. Since I'm not a "Collector" - I shoot my rifles - I don't buy just for historical value.
The M1 Garand has a bit of all three for me - looks good, feels good, has a history. Looks were probably stronger than history for the Persian Mauser, but definitely not for the SKS. I really like the feel of the Swiss K31.
