That first one would be good because it's lower, quail don't need a lot of height ( I assume you are getting coturnix? ) I assume your weather is fairly cold too so either of those would give them some protection from cold and predators. The first one has trays so the poo wouldnt drop , the second one I assume the poo would drop on the ground. personally I like the poo to drop as then I can just shovel it out but I have them with trays too and you have more options on where you can put it with a tray.
Make sure if they don't have hardware cloth that you add it, as raccoons can pull their little feet or heads through anything bigger and it's not pretty.
