I really rate Signatory. For me, they were the best stand at Whisky Live London. Every whisky I tried there was unique and delicious. I've bought quite a few of their bottlings and have not been let down yet.
People say CC is bad. I've had one bottle from them: Tullibardine 10yo 46%. It's very tasty and was cheap too. The only IB I've felt a bit let down by is Cadenheads. One great bottle one distinctly average one. The SMWS is variable, but I don't think they'd claim not to be. Their tasting notes are also pretty honest. If it says struck match on the notes, get your gas mask on
