Both in same time :D

Hard to choose ,depends .if u already had team for one of those it will be easier for you

What's your playstyle? That's what you should look at.

Masked Man is a single unit control, hard hit and can be annoying to deal with.

or

AOE, defensive < This is my playstyle.

For me I would take Deidara. I'm average 87k, strong in generally. But I was never confident with my initiative, even though I legit have 6k.

I am not even top 5 in my own group.

I've always played defensive, off tank bruiser. That's why I fell in love with Roshi.

As long as you've survive a few rounds he will scale hard.

If you have high ini then deidra,jigo,sailor, and earth main. If you have a problem with blitz or hidan, then mm.

Hmmm, I don't think I have high initiative. I don't think I have a lineup for masked man! (what is it again?"

Man. 1 day left to think about it.

Edo diedara if u want to play him for 12 months and keep winning.

If u like changing mains and teams then go for MM because he's very flexible for team building.
