Depends on which argument is "data" (calculated, changes frequently) and which
is control (fixed, or changes infrequently wrt the data).
In other words, if you wanted to make a reusable verb, which is more likely in
your context:
deal =: 3&?
or
deal =: ?&10
?
If the former (which is more common), I'd be inclined to write 3?10 10 10. If
the latter, I'd be inclined to write 10 ?~ 3 3 3.
My inclinations stem from the facts that it is easier for me to scan code if I
know I can expect controls on the left and data on the right, and it's easier
for me to write code if I can incrementally build up data right-to-left, rather
than using nested parens.
But I also have to be wary of the hobgoblins of consistency.

And 3?3#10 is shorter than both, though is closer to 3?10 10 10 than 3 3 3?10.
