[One platform, one yearly cost]

An improvement to IO Bit is the combination of one single application that does all the separate functions (updater, uninstaller, defrag, optimizer, etc.).  One of the major reasons I no longer use it, as well as other family members, is because you have to be mindful and manage all the disparate IO Bit applications.  A single application is preferred with a single renewal. 

An additional recommendation is to co-term all products on the same date so renewal is easy with all your existing products.
