You will only know if you can compute the value in $ the time and effort spent in airdrop or bounty.
I used to be an airdrop junkie. I stopped few months ago and shifted to joining bounty campaigns instead. The distribution date is just the same so while waiting for that time to come, it is better to accumulate more tokens. At distribution date, airdrop hunters get 1,000 tokens (less effort) while bounty hunters get 100,000 (more or less) of the same token.
