I'm not really looking for a "what brand/model is better" type thread, just which one is your "go-to" instrument.
For example, I love playing my Alvarez backpack guitar. It just feels great, has good sound, and is more convenient to travel with. I have a couple ukuleles, but I really want the Cordoba 20-TM-CE because it was amazing to play. I tend to pick up the acoustic Kohala uke now, just because I like the feel better than our other. My Carlo Lomberti Sonata violin is a great little violin for the money. It's sound and feel have been great, even in the smaller sizes that I bought for my kids. (With the same model strings, their violins sound almost exactly like mine except for the volume). I bought McCallum bagpipes, and a Shepherd chanter, and can't tell a difference between it and other types (although having wood is better than plastic, and I wish I had a combo bag with gortex in leather instead of just gortex.)
