sngs r super easy and u can get in a lot per hour.. thus increasing ur hourly rate (which is really what we all want) .. ya the big mtt cash is killer.... but I know guys that grind mtts for a living.. and they can go months without a really big score..
I prefer sngs cause I know positively that if I play x amount of games.. I will make x amount of money... no worries, no stress
good luck on ur poker journey.... never under estimate ur suckout equity
