Engineered wood here, old victorian house so real wood is not an option as it isn't stable enough with moisture/temp changes we have from summer to winter.
Not in any way inferior to real wood if you buy some decent stuff, and ours was actually more expensive than real oak boards.
As above, get one with click fit or similar which doesn't need glue and it's as easy as laminate to fit, will require a circ saw and mitre saw though (will save hours of labour!).
Inlaws have real oak down, looked great for the 1st year, then they fitted a wood burner in the room and the floor really doesn't like it, lots of gaps opening and floor now starting to warp too...
One important thing to keep in mind is the height difference, engineered and real wood are pretty thick in comparisson to laminate, and ensure you remember to add the height (and cost) of decent underlay.
