Waves multi-band limiters, such as the L3-LL and L3-16 has one feature I've not seen in any other plugin:
Priority When it comes to limiting, this is a feature that undeniably can help you judiciously dial in the right amount of limiting for how much the kick drum affects the rest of the mix. I never go overboard with it, and it's not a replacement for a great multi-band compressor, such as the Flux Alchemist, but it's very good with band-management in limiting. VERY powerful and unique plug-in!!
I use the L3-LL when I want to manually adjust the release times of each band, but then use the L3-16 next to perform a general multi-band limiting. Finally, for down-sampling, since neither offer this function, I'll drop in a Nugen Audio ISL 2st to handle any final overs from the output of the L3-16.
