AMD and Intel are basically sort of like equal companies now. Their prices also seem to be almost the same now. Before Intel Core Duo's I would say that AMD was probably the best bet because if you want a laptop with 64 bit processing chances are that you would most likely go for AMD Athlon 64 or Turion 64, but now since Intel has launched their newer ones (even though they might be a lil' late) obviously the newer the processors and chipsets are the better they get.

So right now I'd say that they are equal, but Intel sort of has the upper hand because they've got a newer line of processors.
