For those just dipping their toes into the AAO route, I'll offer my (still novice) experience. The program has some quirks that I encounter from time to time, but overall I love it and I use it for all of my planes. The "Scripts->Watch Simulator Events" can be a great help, depending on the plane. Also, MSFS dev mode toolbar "Tools->Behaviors" is indispensable when it comes to investigating what's happening when you press a button or move an axis.
I started using AAO because in both MSFS 2020 and 2024 I have completely lost my controller profiles several times (once was my own fault, I did a cloud reset and didn't investigate how to save the profiles first). This was extremely frustrating for me, especially with 2024's very laggy controllers menu pre-SU3. AAO has overall been a godsend.
Since getting most of the basics, the only thing that's been challenging enough for me to give up on is camera controls. Just didn't have the gumption for it, so they're all still bound in the sim.
Edit: Also, thanks @HadronFlux for the video, I'll definitely be watching it to see what tips & tricks I can pick up.
