For me its:
 
1. Guitar
2. Piano
3. Any remaining string instrument (from cellos, to Chinese/Japanese/Arabic traditional instruments etc.)
4. Vocals (I really like group vocals too, like hymns)
5. Drums
6. Synthesizer (man-made sounds such as sounds you hear in electronic music)

1. Cello                        Yo-Yo Ma, you amazing person.

2. Sitar                        Hindi
3. Blues Harp               Blues
4. Stand-up Bass         John Coltrane

Yo-Yo Ma? You need some to listen to some real cellists there

I was very nearly a conservatory student studying cello performance, so I suppose I'll rank that as 1. My secondary instrument is the bassoon, so I'll call that number 2. Classical piano comes in at number 3.
 
I love listening to rock music, but I never found guitar, bass guitar, or drums to have any sort of great instrumental qualities to them.
 
Also, I seem to remember this thread existing a month or so ago. Hmm.... Ah, yes, here it is. It would seem my tastes haven't changed much in the last month http://www.head-fi.org/forum/thread/79460/favorite-and-most-hated-instruments/75#post_6905594

Oooh, that will have to be something brass.
 
It don't have to be trumpet, but for some reason solo cornettists, euphoniumists etc. are rather rare

I guess picking a favorite instrument isn't far enough down the rabbit hole for me. I like technique and personal characteristics from the artists. It's like tube rolling, but for performers.

 

[salannelson]

Rhodes Piano
Guitar
Organ (Organs that are jazz/rock sounding like the organs used in The Doors)

 

[Cold Brains]

1) Banjo
2) Mandolin
3) Vox Continental

 

[n3rdling]

I love stringed instruments, particularly violin, guitar, and cello.  Old Hammond organs sound cool too.

 

[Argyris]

Mellotron--I'm obsessed with them.
 
That said, almost every instrument can have its moments. I even caught myself liking the steel pedal guitar used on several Yes albums, even though I normally don't much care for that instrument.

The pipe organ is pretty darn cool as an instrument.  So is a symphony orchestra.
