Just my 2 cents, keyclone for me never worked the way I wanted it, I tried ISboxer and within 15 minutes I had a team up and running through ISBoxer's setup wizard.
Only for ISBoxer I would not be boxing right now.
I was only thinking this morning how awesome ISboxer is and the amount of flexibility it provides.
So for me ISBoxer and Keyclone cannot be compared (I have two keyclone licenses).
Only down side is the subscription basis of ISBoxer but in my opinion it is worth every penny.
