I might not be the best person to answer this, as my dislike of Autosense is well documented on here 
Firstly, I believe that Marvel and Paradise use the same processor. (Edit: oops, wrong on this. I think I was getting mixed up, and it’s Paradise & Lumity that use the same chip)
The tech level of your aids affects Autosense, as extra switching options are either there or not!
I have 3 pairs of M70 and 1 pair of P90 (also had a P30 briefly).
Autosense 4 options:
P30
Calm Situation
Speech in Noise
P90
Calm Situation
Speech in noise
Speech in loud noise
Speech in car
Comfort in noise
Comfort in Echo
Music
Autosense 3 options:
M70

I see you have M90, and P70? In your case, your M90s Autosense 3 will have more switching options than your Paradise Autosense 4! Correct me if I’m wrong, but that should give you Comfort in echo, amd Speech in car??
I consider the number after Autosense as pure marketing. On following threads for Autosense 5 & Autosense 6, I see no change.
Obviously, some of the elements of Autosense have improved.
