Need some advice

I know a lot of people use M105 then M205, but after some research I found a lot of people say M205 is harder to use and has a "learning curve." I haven't bought anything yet, but M105 seems to be tops on a lot of peoples lists. If you have a better idea, please share, I've also looked at Menzerna polishes and compounds, I'm ready for suggestions, this will be my FIRST compound and polish combo, if that helps.

 

i also bought 7424xp with 5.5inches uber pads and menzerna products from Phil. i haven't used it yet and been reading techniques from this forum. i also saw many ppl using menzerna 85rd to finish as well. would be nice to hear the reason from the experts.
