Yes, Max/MSP's [if] object has a more readable syntax. Yet even
with the two nested "ifs" I find it easier to read than your
implementation because I don't have to look up to the inlet to
remind myself which list elements correspond to which variable.
I could put comments closer to each object chain, but then that's
even more objects.

Yes, IMO the way you implemented it is nice because there are
very few wires crossing over objects.
I'd also mention I find it more difficult to patch your
implementation because there are 25 objects (not including the
number boxes), 16 of which correspond to the args of [expr] in
my implementation. That's 16 objects for which I have to change
modes between the mouse (for connections) and the keyboard (for
text).
With [expr] I find it conceptually easier (and more ergonomic) to
set up my [v] objects, my [sel], and my [outlet], then code the
entire algorithm inside one box.
Btw- you can get rid of 3 overlapping wires if you put [value py]
closest to [unpack 0 0 0] and cascade them that way.
