Using "@" is rather "illogical" than "ugly", and at that point it is
not so subjective.
@-mark leads a suffix that applies some "magic" to what comes before
it (e.g. next@{1}, maint@{2.weeks.ago}, and master@{-1}). Making @
a synonym for HEAD means '@' sometimes means a ref and most of the
time means the introducer of magic that applies to a ref.
Worse yet, @{4} does not refer to HEAD@{4} but refers to the 4-th
previous commit the current branch pointed at, so a mnemonic for the
end user to remember the distinction between the two is that a bare
"@" is different from HEAD, which is a total opposite X-<.
This is all water under the bridge, though ;-)

Sounds good.
