Good : Companion 2 is the best in terms of art on the go, I went with the companion 2 I7 8GB ram, and have had no issues (But I do no 3d work so I have no input there).
Bad: It'll function like a laptop for the most part and can handle league of legends at low-med settings with little to no lag, BUT its a very wide screen format so its kind of weird and I would not recommend it for gaming at all.
Summary: If you are more serious about your art and are looking towards doing that for a living then go with the companion 2 I7 as it is a monster and it alone made it possible for my wife and I to do go anywhere at will while still being able to work which is INCREDIBLE!
My 2 Cents: Gaming really should be done on desktops.. Even the 5000$ razer blades have some issues so if gaming is your requirement for the equipment then I would not go with either, but I cannot emphasize strongly enough how great the new I7 Companions 2s are for work on the go.
Something I forgot to mention.....having dual cameras on the companions means you can go for a hike......find a badass composition in nature (cool tree or run down building), snap a picture of it. and go straight into painting over it...INSANE!
