Jon's oval bowls may not be as efficient at burning fuel from a fuel/air mix standpoint but they are more than just "slightly less likely to crack." They have proven to be substantially less likely to crack.
If it's not a truck needing the best fuel efficiency, a set of Jon's cast oval bowl pistons would definitely be in my build.
