Lately I found out that a limiter would kill your snare attack most of the times, because the transient is way more pronounced on snare than on any other instrument (guitars/bass/vocals), so the limiter tends to kill that attack to have all peaks at the same "height".
So I just use L2 (last plug in of the mastering chain) to avoid clippings in conjunction with a linear multiband (waves LMB) or a multiband compressor (c4) to push the mix higher, turning up the gain just on these ones, this way the multiband pushes down the nasty frequencies that are trying to pop out more than the others so you got a balanced mix that it's louder, pay attention this way it's easy to have clippings if you turn the gain knob too high even if you put a limiter after the multiband.
Stop using L2 as you brick-wall limiter, use it just to avoid clippings and you'll be a much more happy man!
