Personally I like the current TR. I see no real reason to return them back to their blasting off every episode selves when it didn't really add anything to the plot and just wasted time. If they do continue after this saga, The best bet would be the simply mix the two versions together and only show them every once in a while.
In all fairness, They have shown in past sagas that they could be smart and successful when they focus on others things instead of Ash and Pikachu. They were a huge success selling things at the various leagues and when Jessie wasn't cheating at contests. So their current personality isn't really a huge change. They're simply not dealing with the two targets that always make them into pathetic jokes.Are you serious? Their serious personalities are still going on?
Man that sucks. Like what's the point of the show anymore? They are supposed to be stupid. How do they automatically become smart and bad just like that?
...this show.. I don't know guys ..
