Well, from my own daily use, I haven't had any issues with 23047. In my opinion 23017 is probably one of the most stable of the 6.5 builds.
23047 is very good, and easily usable for daily use. Of course it's all opinion.
Plus, I really liked his last build, which was 23047. It ran very well. I also love having cutting edge. No one around me has even seen anything close to the work these chefs are cooking up. People who have a Touch Pro see mine, and get jealous! LOL
