I've not heard of "log kit" homes (as opposed to custom built) but I suppose they exist. I would want to consider what species of wood these kits offer - hopefully cedar. If they are similar to custom builds, the cost/sq.ft. of log will be higher. If the plan is to build it yourself from a supplied kit, you have to consider hiring a crane and operator, getting the crane to the site, having extra help to manoeuvre logs, etc. plus some kind of knowledge or experience how to square it up, proper joints and seating, etc. As mentioned, utilities can be trickier unless you're willing to simply attaching them to the inside of the walls.
At least with stick-built construction, each element is more manageable.
