One vs Two: Two IMO can provide a more optimal solution but I recommend you follow the advice of the specialist as there can be more variables involved that may not be present in the audiogram.
Of this list, the Widex Allure 220 is a lower tech device compared to the other ones but some (including myself) love the Widex sound.
Jabra 30/Sphere 90: These devices have the latest and greatest tech for speech in loud environments. They are all good brands and appropiate for your loss.
Many people here will say: Go for molds. I’m more of a “try the simplest that your audiologist recommends first” - It is going to depend on HAs feedback, quality of sound, speech understanding and physical fit.
Yes, HAs can help but they are not a guaranteed solution for tinnitus
