Mega is really unclear how to progress and there are lots of cases. But 2x2 is pretty fun and easy to spam solves in ( like 5bld yo),also it is quite clear how to progress and it is fast to solve and that makes me feel better abt my speed
That is the thing is if you do 2x2 you have to be constipated on that only, by doing mega you get better at other events which may be a plus but u dint think so, I think it is just people being to lAzi to constipate on 1 events
