I prefer swords since it makes upgrading weapons more interesting. There are always legendary swords, longer swords, heavier swords, titanium swords, etc. Compare that to RPGs with guns. Oh yay, I bought a new fictional gun, I can take off more now. Right.
I also prefer swords since it makes the game a bit more realistic. If you're playing a game like Fable or something it almost makes sense that your main character can kill all those people and not die. If you're really really good with a sword and all your opponents use only swords, than you are essentially unstoppable, it would be possible to go though quests killing people left and right and you could escape unscratched.
But games with guns? It takes one putz with a pistol and half decent aim and your main character is dead 5 seconds into your quest.
