Lets say that you have some top-tier freeform shapeshifting ability and you want to create the ultimate form for yourself, what do you change?

Some things to think about
>Legs
Are plantigrade superior to digitigrade?
>Hands
A second thumb on each hand?
>Arms
Are two arms really superior or would you add another set of arms?
>Innards
Would a second heart actually be beneficial? A third lung?
>Eyes
Would you add more eyes?
>Skin
Is current human skin superior for our needs or should we go for scales?
>Wings
Is having wings that could actually carry your weight worth having extremeities the size of a hangglider on your back?
