For me, ← is “Alt Gr + y”, two keystrokes, while := is “Shift + .” and “Shift + 0”, a total of 4.
← is clearly vastly superior, and it's counterpart, →, allows for the variable the expression's assigned to to be on the right, allowing you to code in whichever way's more natural to you (which is a good thing, no matter how many
FIOC-enthusiasts tell you otherwise).
