i like the F# (#11), A9 and B (#11) the you get when you fret the lower 4 four stings on the 2nd, 5th or 7th fret respectively (like a bar chord) and leave the top two open.
The F# is aka "The Rush Chord" since
Alex lifeson uses it a lot (most notably the first chord of Hemispheres)

if i didn't explain well enough, the F# looks like this:
E o
B o
G 3
D 4
A 4
E 2
