Big fan, generally.
Co-op (NOT A SUPERMARKET etc): good cinnamon swirls, excellent maple pecan plaits, but let down by their embarrassingly poor jam doughnuts
Tesco: the undisputed jam doughnut champion, and the tiffin slab lives up to its highly appealing name, but anything with flakey pastry is quite poor
Sainsbury’s: pretty average all round. A safe bet, not no standouts.
Any other opinions?
