An Akorn can do what a Kettle does but a kettle can't do what an akorn does if that makes sense.
check out kamadoguru.com. Brethren JMSeltzer runs the forums and also has a bunch of youtube reviews for the Akron (ManCaveMeals) He can show you how to run the kamado with direct grilling to indirect cooks, to low and slow, to high temperature searing.
I would personally keep the OTS and buy an Akorn so you have the versatility and the a good choice of which cooker you want to use for whatever cook you are doing.
