The CS-3 is a great all-around compressor. Flexible enough to do what er you need. There are quieter/pluckier/more bendable/more transparent/more tweekable ones available, but I'd never feel unable to do what I need if I had that.
If I'm going for maximum cluck and quash tones, I'd probably go Dyna Comp. But there are things that won't do, or let me adjust.
The CS3 has some mods out there to investigate- it has its own unique sound. For me, it is a little too 'pumpy' the way it comes on, but some mods address that.
I used a Marshall ED-1 Compressor for years. It's a pretty good sounding compressor going from lots of squish to very subtle (seemed best set to just even out hard funk style strumming), and pretty full featured. Main problems are that it's noisy at extremely high compression/volume levels and doesn't have a great bypass. They usually pop up from 40 - 60$ used.
I have an ED-1. Until I bought my Route 66 v2, it was my go-to comp. I play a lot of Country, so the comp is always on. Another cheapie, if you can find one is a Danelectro Surf & Turf. They're super cheap.
