We get this "which machine" question often.
Until the Respironics machines had the heated hose I would have suggested the S9 AutoSet if money permitted because the heated hose system was a big plus IMHO.
Now unless someone is using pressures above 14 cm I tell people it's a toss up. Both are great machines and I happen to have tried and own both brands. Each has a few minor pros and cons over the other but none are deal breakers.
I think that at pressures in the teens that the S9 EPR exhale relief might be an advantage but not having it isn't a deal breaker because the PR S1 exhale relief is quite good. Each brand does their exhale relief differently than the other. Neither is necessarily "better" than then other...just different.
Some people might do better with one brand over another but I think most people could use either brand successfully.
Each does a great job preventing obstructive apnea events. The algorithms are different but the end result is the same.
Often the S9 costs a LOT more money but it doesn't mean that it is that much better.
Not many people have had a chance to actually use both brands. Most are given the one machine and will tell you that what they use is the best and they are happy with it. I have actually used both brands successfully and for most people I think it is a toss up as to which machine they would be successful with.
The S9 has a bit of noise on exhale. The PR S1 has a bit of noise on inhale.
Both have easy to obtain and use software.
I do prefer the data that the PR S1 gathers in auto mode just because I like to see the Flow limitations and RERAs flagged as separate events.
The S9 shows flow limitations as a graph which is a bit difficult to evaluate and doesn't do RERAs at all.
Again not a deal breaker and really just my personal preference. I find the Encore detailed report a bit easier and quicker to evaluate because it gives me all I really need at a quick glance. ResScan for the S9 is a bit more difficult to manage and see what I want to see at a glance.
I sent you the information on Encore...here's video that explains ResScan and gives some examples of what is shown and how it is shown.

If the S9 AutoSet doesn't cost an arm and a leg over the PR S1...you would likely like it a lot as I know you would be happy with it but if the PR S1 is much more affordable...get the PR S1 60 series Auto cpap model 560.
Here in the US the AutoSet is roughly $300 US more than the PR S1 and that's a big difference and it isn't worth it unless someone is using pressures in the teens and then I suggest the S9 because of EPR being potentially more comfortable at higher pressures if someone can afford the price difference.
I may have to RISE but I refuse to SHINE.
