The XLR is a balanced connector, yes? (Less noisy.)

Re: Hey electronics/pro-audio dudes.
No functional difference - they'll both give you a balanced line plus shield. XLR's are probably a lot easier to wire.
TRS has the advantage that if you want to go unbalanced, you can just plug in a normal cord, and it will short - to shield. I could see this being a cost saving measure on say, a power amp input, giving you both inputs with one connector. I think the Biamp power amps I owned a long time ago were like this. If you're cranking out a brazillion units, you have to look hard at whether you really want to pay the extra $$$ for the XLR connectors.

Re: Hey electronics/pro-audio dudes.
Rich is right. If they're both low Z (aka +4 dBu) and balanced, there is no real difference.
A lot of pro hardware will give you the option of connecting one or the other. Some even have those cool jacks (can't remember what they're called) that accept an XLR or a 1/4" TRS on the same jack. My MBox has that - its a great way to save space on small devices.

Re: Hey electronics/pro-audio dudes.
Thanks guys. Thats what I needed to know. If you haven't already guessed, I'm experimenting with one of my guitars and going to make it a Lo-Z output instead of Hi-Z. I have a couple of ideas I want to play with. Using a stereo (TRS) jack in the guitar makes things much easier.

Re: Hey electronics/pro-audio dudes.
What kind of amp do you have in mind? I guess I am assuming your low impedance output is going to be balanced - and a balanced output requires a diff-amp input?

Re: Hey electronics/pro-audio dudes.
I'm experimenting with several different things, (just to see/hear the effect), but, for example:
1. Mic input of a mixing board
2. Mic input of a good quality mic preamp
3. Modifying an amp for a Lo-Z input.
There's several benefits to using a Lo-Z balanced line, one of which is this interesting circuit:
Jensen-Transformers - Applications
Scroll down to "Musical Instrument Application Schematics", AS004 pdf document.
Its all just food for thought.
