If you want the most amount of tools and features then Utilities Ultimate, as the name suggests, is packed to the brim making it a great choice for the kind of user who wants a technical deep dive.
The user interface is slick and one of the features is real-time optimisation of your CPU and memory which is unusual. And there are loads of other tools to get stuck into.
However, it under performed with cleaning up junk files and registry issues, too. Considering the high asking price and lack of a single PC option, you might want to look elsewhere.
The price is reasonable for the first year but then renews at a much higher price.
