Is wondershare a good backup program?

I updated to 4.3 last Saturday and experiencing very bad lag and slow response from the phone. Am really disappointed with it.

I just backup using Kies and would like to do another backup for safety purpose!

Question: will saved games be backup also?

I am planning to do a factory reset as suggested by some sifus here...

regarding the lagging of 4.3 update, i managed to factory reset my phone and now it is working flawlessly.

i backup using kies and helium. kies mainly for contact but unable to restore apps and their data.

Helium is awesome and managed to restore all my apps and saved games. Only downside was after restoring Waze, it caused waze to crash. Had to delete and reinstall again. But thats just minor issue.

thanks to everyone for their advice. btw my phone is not rooted.
