Machine Gun.

Red House.

purple haze
has some of the best lyrics ever

Voodoo Child (Slight Return) is my pick for the best Hendrix song.

agreed with all along the watchtower

The wind cries mary.

Castles Made of Sand

Jimi Hendrix
 

Voodoo Child (Slight Return)

Purple Haze :)

My favorite would be Voodoo Child. Purple Haze and Spanish Castle Magic are good songs, too. Personally, I think all of his songs sound pretty much the same, but he's a legendary (left-handed) guitarist, so I'm not saying he's "bad".
