The closet I’ve tasted is Swerve. They have white sugar substitute comparable to sugar, brown sugar substitute comparable to brown sugar and powdered sugar substitute comparable to confectioners sugar. The true litmus test for me is if you can bake with it or put it in your coffee without a bitter aftertaste. These sugar substitutes pass these tests for me. Also, King Arthur Flour has a decent sugar substitute for baking. I’ve not tried it but I hear good things as well about their sugar substitute if you don’t have gastrointestinal issues. Hope this helps.
