Oh alright, I just wouldn't trust Orbit as the company was involve stealing Malwarebytes malware signature database a couple years ago and after they were caught and remove the stolen signature data their anti-malware software became crap.
CCleaner is what I use for computer maintenance but I think you are fine with Orbit for that. You only need 1 to do the job.

I think iobit advanced system has a feature that disable background computer process to free up some cpu/ram usage to make your computer run a bit faster, CCleaner does not have that and I would prefer upgrading hardware then relying those boost feature as they can be disabling stuff you would want it to be running like antiviruses or autoupdate checkers (can customize to whitelist if you know your processes).
