Mixing models left/right like would save a lot of money on programs that aren’t needed. Personally, I preferred Moments over the Oticon and Phonak models I tried… but anyone’s recommendation is going to be anecdotal and personal preference. I know mine is. I gave up Phonak’s better speech in noise for the clarity of Widex, a rare choice.
I think of hearing aid as like shoes - everyone has a personal preferences for the style, fit, feel, etc. Their functionality is where the audiologist makes them work as well as possible for your hearing needs that you have. As you’re already in the price bracket of Widex, trial Phonak and Oticon if you can. Which brand/model comes down to what you like and what works best for you, and that takes trials of options.
