Both are a bit loose in the torque area in that by convention torque values are given as on clean and dry threads, unless otherwise noted, but they don't always remind you to clean and dry threads like cylinder head studs and nuts which will probably not be clean or dry.
Some versions of the Honda common service manual have a excellent section on fasteners and torque, etc, and it is worth a read if you can find it.
And sometimes they both suggest using anti seize, but don't remind you to reduce the torque 25/30% to account for the wet thread.
FWIW Loctite doesn't need any reduction, it is formulated to use the same torque.
Haynes will probably do you for everything you should sensibly be tackling, and his advice on what should be left alone is usually sound, despite what you may read elsewhere on the net.
