It not that I don't like either, I usually use Horde and direct my users to that client.

I just rather not give them a choice, most users that use webmail access, have limited skills and the extra choice always leads to problems. Mod to advanced users seem to perfer setting up a pop account on thier pc.

In a pinch it's great to be able to check mail from any browser and Horde does that fine.

IMO anyway
