I think they are all good really. I use Quiet One 6000's on my 300 and they've been great pumps. Can be run inline or submersible. Mags are good but a little less efficient than the Q1's. Every one will have favs, but mine are the Q1's for submersible and Reeflo's for inline.
Never used a Laguna so I cant way in in that one
