Based on what? His larger than life internet persona? Hubris, the term used by Jeff, is very appropriate here.
There is absolutely no reason to ever have a gear up incident. First of all, flying in a plane with an inop gear horn and not even knowing his OWN plane has a gear horn is inexcusable. Someone else had to point out in his OWN POH. Every plane I fly, I read the POH from cover to cover. Secondly, by following a few simple rules you will NEVER have a gear up. Don't even touch the flaps until you have extended the gear. Never. Always check for the green lights multiple times including short final. I always not only check but touch the gear down lever multiple times reminding myself. And please don't blame the last annual. Has this been your only annual? It is all their fault? How on earth can you own a plane not even knowing that it has a gear horn? Incompetent. I'm sorry to be harsh but you need some major remedial training here.
My take on this? Yes fatigue and lack of a process (checklist or whatever). But also clear to me HUBRIS ("I've got this, I'm a super pilot") and lack of recent experience. I'm sorry to say this it was just a matter of time his attitude in his tens of thousands of posts on this and other sites is clear.
