There really is no one great design/brand/model in sound-cancelling electronic hearing protection, I'm afraid.
I can at least tell you the model that's been widely adopted by the US military: Peltor SwatTac MT15H68FB-08.
Personally, I don't have any electronic hearing protection. I have custom molded earplugs because I suffer from Tinnitus like you do. These are the best but they have their downside too.
I'm looking at those online. Their configuration (bulky at the bottom) would absolutely prevent a good cheek weld on the gun stock. Even mine (Howard Leight Impact Sports) bump and "knock" against the stock a great deal.
