Steve,
The 200 watt coupler will give more resolution at lower powers.
In other words, the 2000 watt coupler covers the scale from 0 to 2000
watts, and 100 watts is only 1/20th of the way up the scale. With the
200 watt coupler, 100 watts is the halfway point.

I'm contemplating adding a P3 to my K3s and the P3TXMON option seems a
worthwhile addition. I am trying to figure out which directional
coupler to select but can't find much if any information between the
DCHF-200 and DCHF-2000. So I don't have any data upon which to base
the decision. At the current time I have a K3s/10 and a KXPA100 amp
and so the 200W coupler would be fine but maybe there's a higher power
amp in my future, don't know. Seems like there must be some
performance aspect that the DCHF-200 has that's superior to the
DCHF-2000 or else there would be no reason for the '200s existence.
If anyone can give a little more information I would very much
appreciate it.
