Hi Samuel,
I have Ozone 8 and N2 and I love them I have to say.
The plugins that are great for me are the Visual Mixer as it leaves all the panning in front of you like a movable picture and the Tonal Balance which compares ur song with the industry norm and you can see where it may not be balanced and then work to correct the imbalance.Also if I am not sure a track needs nuetron I can use a Mix Tap on the track which allows all the communication between plugins still to go on.
So if you can afford it the advanced is very good.

No problem using both together,they are made for each other.The question I have is when using OZONE on the Master buss should I leave it on before going to Mastering stage or take it off.The delimma is that if I leave it on its like double mastering to a certain degree.I would love if Izotope did a specific video dealing with Ozone on the Masterbuss ,pros and cons etc .For me I think you can really go a long long way with BIAB,Izotope and a good vocalist H
