I had this same debate and went with hardwood. I'd caution against laminate if you're doing it yourself, especially if its the whole house (depends on if you do this for a living). I have seen a ton of bad laminate self-installs, and trust me, if it isn't installed perfectly, they you'll end up with a "bad laminate" looking house, people will be able to tell its bad, and you'll have a whole house full of the stuff. There is absolutely nothing more offputting to buyers than shoddy laminate. Why renovate the whole house only for it to look/feel cheap?

I now have a main floor of solid hardwood (installed myself), and carpet upstairs. Best of both worlds and price averaged across the house likely would be close to doing it all laminate.

That said, if you do go for a whole house of it and install it yourself; be a total perfectionist nazi. Make sure everything is proper and sitting on the subfloor/underlay exactly. Even if you have to redo a hundred cuts and end up wasting a box learning, do it, the cost of a few extra boxes of product will be a sound investment
