I have been shooting Bateman tabs for years now, and I recently got a couple of new tabs from Scott Teaschner. The Bateman tabs are great, but Scott's are every bit as good in their quality and performance, and he builds them with a snap closure loop for fitting different sizes of O-rings. And if you prefer to use a different attachment for your finger, a cord or leather loop (perhaps with an adjustable length) can replace the O-ring. The tabs Scott made for me (at my request) have liners, like the Bateman tabs I am used to shooting. I have an arm guard, a knife sheath and some leather treatment products from Scott also, and everything he supplies is absolutely top-notch.
I wanted to add that I have never used the EFA tabs, but I have several of Don's bow quivers. Don is also a guy who provides top-quality products, so I expect the same from his tabs.
