Phonak Nathos to Widex SmartRic

Currently have just started wearing the Phonak Nathos from the NHS (2 week in). And Wow…what a difference it has made to my high freq loss. I have had decent improvement over my tinnitus too.
My one issues is with the slight delay which almost sounds like an echo. Would going provate make a massive difference, espically with the likes of Widex? Do all brands pretty much offer the same or is Widex true no delay?
