Bourbon biscuit - Worse than custard creams and very easy to get sick off.
Custard creams - Not a bad biscuit but not good either, the texture is bland and the cream inside is never truly satisfying.
Digestives - The milk chocolate ones are the best on this list, although it's still mediocre compared to some other biscuits.
Nice biscuits - Very plain.
Ginger nuts - Fine in small quantities, actually quite nice for one or two yet easy to get sick of.
Maryland cookies - Second best on this list, only because chocolate chip biscuits are in general nice, Maryland's version is a little disappointing compared to some other brands.
Rich tea biscuits - Even more plain than Nice biscuits.
