This is trivially inferior. Win the ♠A, and cash the top clubs pitching a diamond. If both clubs live you are cold, cash the ♠Q and in the worst case scenario of west having 2 clubs and 4 spades you ruff the third club high and play ♠K, spade. But you still preserve the extra chance when east is precisely 3=3=6=1 or 3=4=5=1 only at the expense of an overtrick when west has 4 spades and 2 clubs[which should be exactly equally likely as you are just mirroring the black suit splits]. Incidently, this line even survives 5-0 spades if LHO has 3 clubs[of course you find out about 5-0 spades at trick 1 so you'd hardly take a line that doesn't have a chance of picking up 5-0 spades].
