I just landed my first Tuna within the week, and it such a killer piece that has surpassed my expectations. I will be purchasing more in time. BUT- as many have mentioned above, all 3 of your options are stellar watches, and you honestly couldn't go wrong. I have also been tempted to get a AD, due to the rave reviews and solid history behind the brand... It's " THE Dive Machine" for goodness sake, well, at least that's what AD site says.
Side note, I have always been a auto guy... Having a decent rotation in play, a couple winders in motion, and just thrilled that I can grab my Tuna and go with no hassle. I never thought I would enjoy a quartz as much as I do. The accuracy is top tier and it has become my reference for setting my autos when not using my Atomic clock. I am also enjoying the fact that the Tuna is built to handle just about anything one could/would throw at it.
Good luck and please circle back around with pics of your selection.
