It's an old thread but it came up again in a different context so I contribute a little here too.
The point with compressors is that there is no good or bad per sé, it totally depends on material. There are some compressors I love to use on voice, others on cello, and others on guitar. The H-Compressor as well as V-Compressor by Waves are very good on some things, but not so much on CG. You need something that is quick an transparent and does not emulate the coloration of vintage compressors. I have many compressors in my DAW, but somehow I end up using either Waves Renaissance Compressor or Ozone Izotope 5 or 6 mastering compressor; both are very inconspicuous and can be used so subtly that you wouldn't believe there is a compressor in the chain; but when you AB the track, you hear that it helps the music. Recording is not live performance, and making a good recording is an art in itself. Well captured material is the first step of it, of course!
BTW Izotope has also a kind of multiband compressor that can be very helpful. But as every multiband compressor, it should be used very cautiously.
For EQ I can't think of anything better than Fabfilter Pro-Q 2. You see immediately what you do (and hear, too
And talking about digital tools, here one another that might help you improve your record: Flux StereoTool. Its free and it's fabulous to correct spatiality and L-R-Balance problems.
Music is a big continent with different landscapes and corners. Some of them I do visit frequently, some from time to time and some I know from hearsay only ...
