They are pretty trick, but I think the biggest thing you have to decide is are you travelling or not. If you are, to me it's a no brainer. These things look like they fit a ton and hold up well.
If you aren't then honestly, any old thing will work. Go for one you like best and get it. I've had 20 or 30 different containers over the years. Currently I have a Racers Edge hauler and a cheap psuedo footlocker thing from Walmart. I really need to consolidate though because I can't fit everything into 2 things. I always still end up having my radio bag and car sitting on top =\
