Freshwater salt vs ozone (ozonator)?

I'm not sure who is telling you these things you mentioned above but the reality is the chlorine is going to do the sanitizing, plain and simple. The ozonator is a nice add to a chlorine system to help you maintain clean water IMO but it won't reduce the chems too much and make no mistake, the chlorine is the "backbone" of the system (to use your phraseology), not the ozonator!
You're looking at choosing between a simple, manual chlorine system with some help from an ozonator or a salt system that creates/maintains it own chlorine level. Either system is fine but if anyone is trying to sell you on a system with the ozonator doing most of the work then they're either uneducated on hot tub water care or they're using salesmanship to tell you what they think you want to hear.

Got it. My assumptions on the ozonator is based on conversations I've had with dealers and with ratchett's comments above. But I'm just learning here. If the ozonator is just a supplement to a chlorine (direct or salt derived), then it hardly seems worth adding that component at all.
On the other hand, this site https://www.loveyourhottub.com/better-water-blog/salt-or-ozone/ seems to indicate an overall lower requirement for chlorine concentrations with ozone vs salt system (.5-1 PPM vs 3-5 PPM) which seems good if one is trying to avoid chlorine.

If you look at that website you will see they sell ozone systems but not salt systems. That’s most likely why they push ozone

Absolutely. Everyone's got their agenda. I'm trying to cut through that and understand the true differences.
One of the best ways to do that is with math or numbers. Do you know if the chlorine concentration numbers mentioned on that site for ozone vs salt system (.5-1 PPM vs 3-5 PPM) are accurate? If so, that seems like a pretty big difference and could possibly make the difference for odor and skin sensitivities.

I would think you would need to keep about the same levels either way. Ozone will also oxidize chlorine so you in theory would need to add more to keep a residual level. I have a Fresh water salt system on my personal tub. I keep the chlorine level right around 3.

I think ozone will improve your chances of keeping the water clean/clear and lessen the chance of frustration so I like it for that reason but where did those numbers come from? I don't think there is a difference, you need to raise the chlorine level to the same point either way from what I know (not my real area of expertise).
