Double dummy analyser: makeable contracts
Although you have fewer clubs between the two hands, the club solidity swings the balance towards 7club. The spades will be 4-0 just under 10% of the time, whereas a 5-0 club break will occur about 4% of the time, although adjustments have to be made for the opening lead being ruffed. Nevertheless, you would still make 7club on a 4-0 spade break, assuming that the clubs were no worse than 4-1 and an opening spade lead was avoided.

That's all very theoretical, because the true match-points partnerships will score hugely for playing in 7spade or 7NT. One for a bidding challenge.
