Well, I generally conducted retroairdrops and LRT staking airdrops, and I rarely participated in launchpools because they pay extremely low APRs and the size of your reward is entirely dependent on the amount staked in the launchpool. I just retrodropped by connecting my money to an actively used environment, and I received tokens as a consequence. 
I believe redrodrop is much more worthy than launchpool, but there is no guarantee that you will always be qualified to get the reward once the project's developers have announced their TGE. Finally, retrodrops is well worth the time and money spent if you were eligible for the reward. 

Launch pools are useful when you have a large amount of money to stake, but they also provide a guaranteed payoff to even the smallest stakers. I've risked a few thousand dollars but received less than $60 through Launchpool.

Launchpool is terrible for me.
