The Gator bag is a step up from most gig bags in terms of padding/protection. I was on the fence about just using it for my airline flight from Utah to Florida last month. I wanted something with backpack straps for "hands-free" carry. In the end, I decided that the Gator wasn't quite enough for the overhead bin on an airplane. I got the Reunion Blues Continental which is a hybrid between a padded gig bag and hard shell, and it has the stow away backpack straps.
I did try the Crossrock zippered ABS case first. It has D-rings that I could have attached backpack shoulder straps to. However, the inside dimensions of the case were no where near a fit for the Clara. The Clara body would not fit inside the case at all. I have returned several cases to Amazon recently that had real life dimensions that didn't match the dimensions listed on their Amazon page.
Except the Clara, my other ukes live in hard cases in my office. Mainly because I live in a dry climate and have to humidify. They are lined up, standing against a dresser, and the cases protect if they get knocked over. I use gig bags when I take them out of the house to play, because I'm almost always carrying a lot of stuff and the gig bags have back pack straps. Gig bag on my back, hands full of gear. However, if it's snowy and icy out, I'll stay with the hard cases. I have a vision of me slipping and falling and landing on a uke.
