GF, SH and SSI all for different reasons.

GF- consistent, I almost always get one, higher payout, can tell them if there is an error.

SH- instant gratification baby!

SSI- usually is an easy one for me to get, and has good topics.

I love MV when it likes me. YTC is fine, just sometimes on the longer side for a smaller payout. Amp. Well. When it credits, I love it.
