I'd recommend staying away from cork for several reasons - first concrete can get damp if its on or below ground level, and cork being a naturally porous substance will absorb that moisture and allow mold and spores to breed. Also, cork itself even if treated doesn't really provide a good wear surface, I don't think anyway.
Laminates are interesting, but I've not tested them acoustically so I cannot comment on how they add (or not) feel to a room, but some of the more elaborate products are darn nice, and fairly reasonable. I must say I am a fan of Armstrong's "Swiftlock" in particular - this product has a better wearing surface than pergo, its locking system is nicer than pergo (its not a tongue and groove, its more of a tilt, slip, tap, lay flat method). The panels drill and cut easily, and are fairly chip resistant if you cut them on a table saw with the flooring surface facing up (or down if you're using a circular saw). You can drive nails through them to mount mouldings and such, but expect to beat the snot out of the nail - its a very tough material, all synthetic. They make it in many, many colors, shades, grain patterns, as well as various stones. A box gives you a hair over 20 sq feet, and costs about $45-60 depending which home center you visit. Not unreasonable.
The only thing that is annoying, is you have to "tilt, slip, tap, lay flat" an entire row at a time, because of how they fit together. Which means it's by far easier to lay Swiftlocks down across the width of the room, unless you have helpers. A friend of mine asked me to help him lay this stuff down on the first floor of his house, which is kind of "T" shaped, and it was fine until we had to lay rows across the living room, foyer, and the 30' hallway to the bedrooms. Got a little tricky, but just required more hands. The total span I'd guess at that point was about 50-60' or so. He really wanted the wood pattern to lay in this direction for some reason. I would have done it widthwise to make installation easier. The surface of the swiftlock is textured, so when light hits it (especially halogen) it kinda doesn't look like engineered flooring, as there are microscopic nooks and crannies. Sweeps or vaccums easily and it doesn't stain (I spilled coffee on it during installation, you should have seen his face... but it came up with a cotton rag with some fantastic). Glue and nails are not required, but feel free. Lowes doubles the warranty if you glue them together instead of just locking them, according to the instructions.
pergo is another decent brand, however I put some down in an incredibly tiny bathroom last summer, the dimensions being 3'x4.5', and already the pergo (a dark cherry) looks like its been beaten to death. I think this is because that bathroom is humid as it has two exterior walls that the insulation is marginal at best, and the furnace is right underneath it. Dispite my taking the time to glue it down and the boards together per the instructions, its starting to pull up at the edges and look atrocious. Once I helped my friend do 1600 sq foot of the swiftlock I'm sold.
That takes care of engineered flooring. Wood. Wood in my opinion looks, sounds and feels the best because it is.... well... wood

The floor I put down in the studio is beech, tongue and groove, glued all around with a nice wood glue that's resistant to moisture. Woodfloors tend to be thicker than engineered flooring. But I like wood. I enjoy cutting firewood not because I like over exerting myself for hours on end, but because I like the smell of wood. Someone needs to make a mahogony smelling candle. I'd litter my studio with them.
Wood requires some care however, you have to polyurethane (after staining if you wish) to protect the wood, then you have to deal with the poly smell for about a week or two depending on your climate. 10 years from now, you'll probably be refinishing the floor after rolling chairs, amps, furniture etc across the poly coating. Engineered flooring, at least the good stuff, seems to wear better from what I can tell. My friend's house got new swiftlock last year, and not that I've looked at it with a magnifying glass or anything, it still looks new. I know their son has taken his bigwheel through the house several times dispite my friend's hollaring.
Hope that helps.
