As this is a laptop, PC-BSD could be a good choice which is FreeBSD tuned to desktop usage. Plain FreeBSD is also not a bad choice. The other major BSDs have clear niches while FreeBSD is probably the best supported, most popular and is strong in the broadest range of areas. I wouldn't bother with something obscure like Ubuntu BSD unless you're actually keen to help out with improving it. I'd find the opposite more interesting: some sort of BSD/Linux.
