The odd
14-26 with the
30-39-49 at typical flat road cadences.
Extremely close shifts, but this needs lots of chainring shifts in the 10 to 20 mph range. Annoying.

Compare to the
30-39-49 with a
13-28. (Campagnolo liked to use the 13 as the smallest cog in 9 or 10 speed cassettes.)
The 39 has a better, wider range of speeds. And the low gears are better too.
Compared to a
53, the
49 lowers the big chainring shifts about one rear shift. That's pretty good.
