Not quite. 60W over 120 diodes vs 60W over 288 diodes, means the 288's are running at roughly half the current. That increases their efficiency by around 10%. That means 10% less heat at the board surface with the 288. BUT - the 120 has quite a bit more surface area, so temperature wise, its probably a wash.
But the price tag of the 120 is so affordable, and when it comes to international shipping the heat sink shipping prices are ridiculous. All and all, the best value for money for a non US based cabinet/tent grower like myself would be in stacking the qb120.
