I think it is a personal thing where different folks will get some differences in results...
For me I found it harder to to get used to the S9 and I found I needed higher pressure on it.
A lot of it comes down to likes and dislikes - with there being no definitive answer that one is overall better or worse.
From my point of view for the PRS1
The swiveling top hose connection - made it easier to fit the unit on my small bedside table.
The humidifier which is easy to clean and seems very robust robust.
The menu system which displays a lot of information.
The Power Pack - small and light.
The carry bag
The price of Respironics Software (thank goodness for SleepyHead)
For the S9:
The Climate line system.
The very quiet operation.
The carry bag.
Large heavy Power Pack - I travel a lot and every kilogram counts.
The fiddly humidifier tank.
ResScan software - it is free but not as good to use for me as Sleepyhead
In the end I bought the PRS1 and a third party heated hose that has a a Y-Lead to power it off the PRS1 power supply without a second power pack.
I pretty much agree with your assessment. I haven't lived with the particular Respironics machine that you had, but had a sister less frills Respionics Plus C flex for a few weeks. That machine had a display that was nearly impossible to view at night, even though it was illumninated. Perhaps, your machine is different. I really love the S9's color display and interface, even though the learning curve was a bit longer than for Respironics. I like that you can control temperature and humidity separately with the S9 and Climatateline tubing. Perhaps with your add on set-up, you can do that, too.
I agree that the water tank for the S9 is not as good as what comes with Respironics, but the non-disposable version of the S9 tank is nearly as good; the top comes off.
I thought the swivel hose attachment on the Respironics humidifer was a good idea and was worried about that when I switched to an S9. However, with the S9 kept near the front of my night stand and away from a wall, there is plenty of room behind for the hose to make any turns towards my bed. Slimline and climate line tubing is so flexible that you really don't need a swivel. The full size tubing that came with the Respironics machine was another story. It needed the swivel. The only problem with that swivel and hose arrangement is the tubing runs over the top of the machine's display, making you have to move the hose to see the entire display.
Another thing that may or not be important to you, but which is better on Resmed machines, is what happens when there is a power outage.
With Resmed, if there is a power outage, when power returns, the machine picks up where it left off. If it is running, it powers back on running.
With Respironics machines, if the power outage is longer than about a minute, the machine turns back on at the main menu. This feature of Resmed was a deciding issue for me, because I am Sabbath observant and prefer running my machine with an on-off timer, rather than leave it running all the time on the Sabbath as I had to do with my Respironics machine. While running any xpap machine constantly won't hurt it, the noise is disturbing.
Software preferences are rather personal. Fortunately, you can run either Rescan or SleepyHead with the S9. I prefer that Rescan reports median pressures, rather than average pressure readings that SleepyHead reports. Furthermore, you can call Resmed to get help with the software and interpretations, if you need it. There are good online tutorials at Resmed to help you get more out of there software. For other matters with the S9, it easy to talk humans at Resmed, too.
Respironics has customer support, but all of it is via email. I haven't found a phone number where I could actally talk to anybody. Perhaps I just missed it on their website. Obviously, they can only help you with their own proprietary software, which is an additional cost.
BTW, as far as noise is concerned, according Respironics, they report that their machines are quieter than an S9. It is interesting that you don't think so. I really didn't perceive a difference. Actually noise levels can be caused also by your particular mask or pillows. I found my nasal mask added noise that I thought was the machine's fault. When I switched to pillows, everything was much quieter.
