This is all massively system dependant. On some systems when the system
is in the same idle state in the lowest power idle mode as in suspend
however as a result of not doing the suspend (which causes Linux to
quiesce most of the hardware) many more things will be able to generate
wake events. On other systems you will achieve a lower power state by
using suspend for various reasons, some fixable and some not. I rather
suspect Arve was talking about the former case.
