No need to ask, CCleaner is really on the top that's why its been more recognized by lots of audience.
1) Fine tune cleaner (not agressive)
2) Registry cleaner (not aggressive)
3) As far from concern, no bad updates which cause system to produce instability using those tools.
But another worth to try is SlimCleaner which another good alternative (without registry cleaner) and I've used with no problems long time ago.
