After reading my brother Jed's post, I should point out that I use Intellitouch in session settings, but I always use my Boss in lines onstage for all the same reasons that Jed does. I have three of them set up for the stringed instruments I use (6,12 guitars and a bouzouki). In the stage environment it is crucial to be able to tune quickly and accurately. I also use a Boss tuner on my Uilleann pipes when I am tweaking them. Hard to beat them.

But for the situation that is being asked for here, I believe the clip on would be best.
