UDK vs Shiva3D vs Unity3d

I am still searching for a good comparison of these game engines and i can't seem to find any... What i did find is that:

UDK has the best graphics,

Shiva3D has most platforms to publish games on and

Unity3d should be the just all around good and not really best at anything...
well for now im sticking with the Unity3D mostly because i already started the project there and it will be a great pain to redo all the stuff i made and i do kinda know to use Unity3D compared to the other two.

Insenia the game

Well... Story for the game is almost done and the name will be Insenia. I have done most of the "basic stuff" and uploaded it on my free website just for testing... I will post the link as soon as i find at least one good reason why not to. Because there needs to be a reason that every single game is not open from the in-dev stage. Well i did made the gui, map, lvl template. Right now i am making Hero template and a "hero select screen". By the way, i am writing these post mostly to check on my progress in about few months, but it seems i forget to post that often...
