Definitely true. Tenor player in our Big Band had a beautiful Custom-Z in a beautiful leather gig bag. Now he has a Custom-Z with a crease in the bell and a new hard case.If you love your horn, go for the hard case. If you love your tech, go for the soft one.
I have my alto in a Protec shaped case. It only cost about $125. It's light. I carry it over my shoulder. The shoulder strap broke once and it crashed to the concrete floor. No damage to the horn. They come in 3 or 4 colors, not just black.I only have one soft case that I use and thats for my curved soprano which doesn't get to be brought out much anyway. The reason is that I couldn't find a hard case for it otherwise I would have preferred one. Mind, not all cases were created equal either! Some of the older types are, in order to accommodate different types of horns less than perfect because sturdy thought they might be , they allow too much movement inside. Also some other hard cases are sturdy but very heavy too! This is not a problem for me if I have to carry the horn form the car to the place where I am playing (via bus from the parking sometimes) but you definitely want to consider weight and bulk (or the possibility to carry the case on your back) if you have to cycle or walk longer distances. In my view, all in all, the best allround cases are protecs . Hiscox might be the sturdiest one but it is definitely not the most practical to carry around and on your back.
My SML alto fits really well in my SKB440 - not a significant amount of rattle for me. But the two latches do bother me. They definitely aren't the most secure.I love the weight and dimensions of skb but the horns don't really fit very snugly and rattle too much in it, the latches (only two) are also not very secure
