i run a Fluval SP6 submersible on my 150, haven't seen any submersibles rated higher than it GPH wise and especial at its small size

Laguna is supposed to be very cost effective and I like mine for good flow and low noise as well. I took it out of the cage and hooked it to a box filter

I use only Eheim and sicce. Sicce have extreme flow. They are very great quality.
