Personally I prefer to use a non-iterator style, so I combine (my own) zip with pair from List::Pairwise. 

for (pair(zip($array1, $array2))) {
    my ($x, $y) = @$_;
    # It's often descriptive to name the values.

    ...
}

The main reason I like pair over natatime is that it's easy to combine with any expression/subroutine that requires the whole list and in particular sort (but also map and grep). For instance: 
for (
    sort { $a->[0] <=> $b->[0] or $a->[1] cmp $b->[1] }
    pair
    zip($array1, $array2)
) {
    my ($number, $char) = @$_;
    ...
}

The reason I don't use zip from List::MoreUtils is that it's prototyped with (\@\@;\@...) which I find counter-intuitive, as I imagine you do too as you passed in $array1 instead of @$array1. It's also more in the way than it's helping, as I frequently end up with wanting to zip the result of an expression instead of an array or having a list or an array holding array references.
