Both are good, education has it own advantages and acquiring a skill is also good in its own way. However it all depend on the country you are from and the economy of your country, here in Nigeria, going to school doesn't mean you will make it big, in fact I have seen countless graduates riding commercial bikes and doing all sort demeaning jobs, some even go back to learning a skill after graduating, but acquiring a profitable skill will put something on your table on a daily basis.
