i've been using eq, comp, limiter and tape head for the past 3 years.
eq : most of time i prefer digidesign eq3 which is way more easier to tweak (and visual), especially on tricky stuff like voice and acoustic guitars
comp : yes, everywhere. it just does the job, easy to use, very effective but still subtle at the same time
limiter : BAM !
tape head : yes, not everywhere, not too much - obviously it depends on the original material.
overall : KILLER plugs for the price. love the garage concept.
i use digi free stuff and massey. nothing else.
I also use his free stuff
