I have used all those on different platforms. So far to date without a doubt is Combat Manager as it works on all platforms. It is by far the easiest to use too and customizable. The Minion 5E program has a horrible user interface and requires too much clicking everywhere which slows down combat flow AND you have to create an "Adventure" profile and put encounters in it, etc. Combat Manager gives you that option but you're not forced into anything like that. Using CM with 5E I am simply deleting the +REF/FORT etc stat block or just leaving them as they're not needed and simply put in the max HP, AC, and Dex (Initiative) mods so I can track initiative. I don't modify all the detailed damage and power stats, for that I just look my PDF file or my Monster Manual. I have no hope for the official D&D program to come out anytime soon nor the 5e Minion, but the official product from WOTC at least looks interesting.
