Channel strips: nice to have EQ and comp within the same plugin, makes mixing easier. The EQ is not very subtle, it brings out a growl that is sometimes useful and sometimes a little much. It's not the EQ you will choose to fix that one annoying frequency. The channel compressor is my favourite part of these plugins, it's a compressor that allows for some moderate to wild sqeeze before the sound gets weird, nice! Turning the knobs using mouse is a bit fiddly, this plugin would probably benefit from an external controller to streamline the work flow.
Bus compressor: I have to admit that this plugin was a dealbreaker when I decided to buy the set, the sought after SSL bus comp! It's even more transparent than the channel comp (which is expected) and sounds good on almost all settings. I like to mix in subgroups, so in a full mix there might be 4-5 instances of this compressor running, in parallell and series. As long as you keep the ratio on moderate levels, this works wonders.
Overall, a good toolkit for mixing. Definitely adds flavour, but almost always in a good manner.
