This would be an interesting subject for testing and discussion.
I use the EQ10Q plugins you linked and they seem to work well,
particularly the EQs and gate. X42 plugins work nicely along with most
of the Harrison ones. AVLinux includes hundreds of plugins and it's
impossible to try them all although I've been pleasantly surprised by
some previously unknown ones such as TAL and Dragonfly reverbs.
Some other plugins I've tried and abandoned quickly because they just
sound bad. Hard to tell whether that's bad DSP or just unwieldy controls
that that make it difficult to achieve the desired result.
Some actual scientifically valid testing would be illuminating rather
than just perception of quality as a user.
