They've abused the word "analog" from the beginning, and even though iZotope is one of the few companies you can consistently trust to get it right, the analog talk is still mostly marketing hype.
I've been an Ozone user since version 2, but stopped upgrading after O4. O5's new intelligent release mode didn't do anything for me except gobble CPU cycles for breakfast. The prettier UI wasn't enough to justify an upgrade, as I'd become quite comfortable with the old one. Promises of more transparent aggressive limiting is a feature I rarely need, and when I do Pro-L fills that role nicely.
But I'm definitely going to demo O6 and just might spring for it. I've been tossing coins into a vase since last December and probably have a hundred bucks in there by now.
