Android: KS Mobile or Qihoo security applications?

There're two strong Chinese companies developing security applications for Android.

1) KS Mobile: CM Security - FREE Antivirus and Clean Master (Cleaner) FREE (two applications but they're cross-referencing each other)
2) Qihoo: 360 Security - Antivirus FREE

The said applications have tens of millions of downloads and almost the full 5 star rating on Google Play. 360 Security includes in fact all features which have the two KS Mobile applications, hence they're comparable. Therefore I would like to hear your experience, pros, cons etc. on KS Mobile and Qihoo applications and especially which do you recommend to use and why.

Also please feel free to cast your vote in the poll.

Thanks & regards!

 

Qihoo UI has butterflies, folding doors, lots of pretty colors - looks like a coloring book. Never quite sure where to look to find settings, not quite sure exactly what it's doing.
KS/CM has a normal looking UI - pretty straight forward.

 

Have to agree. It resembles picture books.

 

I use TrustGo Mobile Security & Privacy.

 

My license for Eset is about to expire so I'm giving KS Mobile a test drive.
I've tried 360 before, was not overly impressed.
