Practical effects will always trump CG in my opinion. However, I am very old school when it comes to films. It is part of why I can barely stomach anything in theaters nowadays. If my brain detects CG, I am often completely taken out of the scene and I just lose all interest.
I'll take bad practical effects over awesome CG any day. I am in the minority I know. I just love knowing that what I am seeing exists in some form. I can also sit there and appreciate the work that went into making a shot work via a combination of camera tricks, miniatures, puppets, etc. It all makes me appreciate a movie so much more. A little bit of CG to clean things up isn't the end of the world, but I feel no matter how good it is. It won't ever compete with filming on location, and the construction of elaborate sets.
You also get a much better performance from the actors. If they can see something, it really helps. This is true of filming on location too, actors look hot as hell in a desert environment? Well, they probably are! It just helps my immersion into the film. Therefore, I hope they stick to this. Even if the prequels were a mastery of storytelling(They aren't.) I would never be able to get into them because the entire thing looks like a video game cutscene.
Rant over.
Also, no jedi please.
