The virtual SSL console in Reason sounds interesting. It may be similar to the Harrison Mixbus DSP mixer. No such thing in Logic Pro X, but I like to use the UAD Unison Preamps & Channel Strips or the Slate Virtual Console Collection to add some colour.
Good point about gain staging. I use Klanghelm VUMT at the default -18dB on every track. It especially makes a difference when using (UAD) plug-ins emulating hardware.
