Is mumu player a good emulator?

I know a variation of this question has probably 1000 times but I want to make triple sure since I am gonna download this on a new computer that's coming in.

(I really to play cookie run kingdom)

.At first I thought,LD player was safest emulator though has issues of breaching/hacking people's accounts.And I am definitely not gonna install bluestacks again after it overheated my current computer

So far mumu only problem is that it crashes sometimes but I want to be make triple sure.Not mention,it doesnt to have the games I want to play on the website though I am just assuming some of apps don't appear on the site(I hope that's the case cuz there's an upcoming gacha game I want to play)

EDIT:
And before anyone adds,yes I do know mumu possibly steals your data(and turns on your webcam)though to be honest, the "data thing"doesnt bother me too much.Not mention I usually have my camera taped over.
