I purchased the XL 2.0 bundle (with terrain).
I found this set while searching for some dual display/travel cases and it was on par price wise with some of the other ones I was looking at, but seemed a bit more functional for travel than some others I was looking at.
I ended up going with this one because it wasn't completely made of the acrylic that I saw so many others made with, and because it seemed more manageable for travel. The adjustable heights for the trays was also a big factor. All said and done I have over 5k points of models that fit in there.
The MDF plus all the metal trays inside does make this a bit heavier (especially since I have a decent amount of metal models) but overall its not difficult to transport - I would guess even filled with models it's not over 25lbs, but how far do you really need to carry it anyway? It's a lot better than lugging around multiple containers and cases that I had before, even if those were less heavy. I would like it if there was an option to put some rubber feet on it or something, but that's an easy enough aftermarket thing to get if you want them. Giving it some wheels and a handlebar like a luggage case would be awesome too.
I haven't yet gotten to building the terrain, but the same material is used for the terrain as the case so I have a good feeling about it's durability.
My only detractor is with the magnets that come with the metal trays. It seems to be a combination of the magnets being just slightly shorter than the height of a base (it doesn't make direct contact with the tray when just glued in) and possibly a magnet strength issue. I was having to use several magnets on my bigger models (about 6), but for all my infantry they have been fine with a single magnet. Very minor issue and nothing too bothersome.
