Which Yakima cargo basket?

OK so I have another question about accessories for my truck. You guys were right these things get expensive, but it’s a bit addictive!
So I’m looking at Yakima cargo baskets and I’m thinking about either the megawarrior or the large offgrid. I can’t really find what the major differences are between the two. It looks like both have ample storage and you can mount things to both. Can one handle more of a load than the other? Does anyone have either of these and can give me their reasons for choosing the one they purchased?
Thanks again!

 

Was hoping someone could provide some insight. I have basically the same curiosity

 

One is a box. One is open in the back. Depends on what you are putting in it.
