Interesting analysis, and facts on $1 give me new lesson. I know that $1 and friends are special, but that's it. With the context provided, I obviously prefer the assignment technique. The only reason I would go with push and while is perhaps, if I needed to check $1 againsts some condition prior to deciding to push it to the target array.
