I personally only use the EQ section. The limiter is good for specific types of music but I rarely find myself reaching for it. The intersample peak detection is terrible - it does something to sound that I don't like. I do actually like the MBIT+ dither, though.
I prefer Ozone 5 to Ozone 6 simply because of the way the spectrum analyzer in the EQ functions. I like to be able to see the mid and side graphs together on the same page simultaneously in an overlapping fashion. As far as I can tell, Ozone 6 does not allow you to see them together in this way. The mid and side graphs have to be viewed separately by toggling between them. It's no good for me but also it is a personal preference.
