Taste buds as well.(smiley face)
I love Everards Tiger - always make sure I have a pint whenever I'm in or around Leicester and remain baffled by the low regard it seems to be held in on this forum.
I don't mind it either but, as with all beer styles, there are good and less good traditional brown bitters and, I find, a well kept pint of Tiger is definitely one of the good ones. Same with Bass for me.
I won't risk controversy and list the shockers but Bombardier, not seen so often now thankfully, tops the list. Perhaps Marstons have sussed it.
