Latest chipsets?

Including all companies, which aids have the latest chip sets? I finally am going tomorrow to try some different HA’s and have been studying this forum for weeks. My current audi only offers Phonak and ReSound, but, if I am not satisfied with what is available there, I want to try either the Epoq or Vigo. I want to know about chip sets to be sure the aids will be serviced as long as possible.

well most companies have their new chipset already deploy,
but it is not so the chipset but also the audiology behind the instrument…

Phonak and resound are good, Phonak is expensive (generall rule) and GN has always been cheaper … I must say GN seems like they are coming back big time, Mostly impressive the BE and the New Nat. directionality… I like any company which contributes to the field of audifology… I believe Gn Air was the first open fit instrument …
