Generally speaking, a laminated guitar will be less susceptible to temperature and humidity variation, but very few Luthiers bother making them. People do claim they sound inferior, but I believe that's a generalization, one which is not supported by my experience in every circumstance.
Factory guitars that are built with laminates are often much cheaper than all solids. If you're planning to travel, gig and play outside, a solid top might be too precious of an instrument to risk, whereas a laminate might have more durability or be easier to replace.
There is certainly a mystique and almost legendary status to all solid wood guitars. Whether or not this is relevant to the quality of the guitar is up to the individual!
I think it's also important to know the purpose of the instrument to make the right decision, as a hand built solid wood instrument usually does cost (up to quite a bit) more, but determining the real value is something open to interpretation.
