WHICH - MKC75 Tri Mode vs Zoom75 Tri Mode RGB fun

I am having similar issues to decide why the MKC75 Tri Mode vs the Zoom75 tri mode would be best option. the features of Zoom with the LCD screen and altering to say a knob or badge etc are compeling but are they really needed. A knob is so useful for macros. As new I can not know with out experience users of both to give some input. Why Zoom 75 and Why MKC75 -

FYI I game, program and will also use for work. Not a hard core gamer to to note. All advise welcomed
