Help choosing between Phonak Lumity 90 and Infinio 70

I have mild to moderate binaural sensorineural hearing loss and I’m choosing my hearing aids for the first time. I went to an audiologist who had me try Phonak Lumity 90 first, then Infinio Sphere 90, and then back to the Lumity 90 (about 3 weeks with each). I’m trying the Lumity 90 again to better compare it with the Infinio Sphere, since the costs here in Italy are really high (€6k vs €9k for a pair) and I don’t have any way of getting reimbursement.

My experience with the Infinio Sphere 90 has been mixed: when the device switched to the Sphere programs, I felt lost, but when it was on the non-Sphere programs, I actually heard better than with the Lumity (which I’ve noticed more now that I’m trying the Lumity again). With the Infinio, I also had issues with a receiver that was a closed dome shape, compared to the one I used in the other ear (and with the Lumity), which has a smaller dome with several openings. The closed dome receiver kept slipping out of my ear canal, even though I inserted it correctly.

I must also say that I was the first user that I tried the Infinio Sphere at that audiologist since that model is available in Italy only since the beginning of October, so the audiologist might be inexperienced.

Now I’m trying to decide which model to buy, and I was thinking of getting the Infinio (not the Sphere, since I did not like the Sphere programs and it costs too much) level 70, which would only cost a little more than the Lumity 90 (about €1k), but I’m not sure if it’s a good idea to go for the newer model but downgrade the level.

What do you think? Any experiences with this?
