I picked it because it just has a few simple buttons on the home screen that do exactly what they say..it's a big WAF-factor there. I don't like submenu's popping out when you hover over a button. That's what I also disliked about Kodi for a long time.You also can use TVE 3.0 inside MP2 Server and use Kodi as client on some devices too. The TVServerKodi plugin needed for this is working with both, MP1 and MP2 since some time. So using Kodi is no reason for stick on MP1 and also no reason for change to MP2...MePo TV3 server support is working pretty well with Kodi too.
By the way, I can not understand the hype about Titan. I never liked the "Candy Store" look and feel. Way too flashy... I prefer the content over the skin, but with Titan the skin is all that is gathering attention. Not what I want to look at daily.
Also it is easy to remove any buttons (a little harder to create new ones, but doable with multi-shortcut).
