The MXR 10 band covers more of the frequencies that I use on bass when compared to their 6 band. The Boss has the frequencies that I use, in a small format, but I find the MXR to be much cleaner and better sounding. Also, my Boss has a noticeable buzz but that may be a defect...
One thing to note, my MXR 10 band requires 18 volts which is a pain in the ass. Much prefer 9 volt so I can use the one-spot.
To echo another post, the Empress Para EQ is by far the best that I've tried. You can use your ear to find the exact frequency that you want to boost or cut, and it has three bandwidth (Q) settings. After using parametrics (rackmount) for many years, I was hard pressed to move to a graphic pedal... until I found out about Empress - here on TB of course!
Compressors is a much bigger topic, there are so many available. Bongomania's page is a great resource.
