It's funny - I'm not sure if there's a major difference between the handling on the PS3 and mobile, but I've found I can save the ball on many of the bad left hand kick outs just with an instant reaction with the left flipper to just catch it on the tip and deflect it over to the right. It's a real just pure instinct reaction save though - there's no time to think about it. You really have to be paying attention though - if you're caught off guard at all it'll go between them. And there are some that I don't think you can save without a nudge, but those seem to be in the minority. Any time the ball if coming down the left I'm waiting it as it comes down and preparing to react if I see it start to kick out at all.
I do think the behavior is pretty aggravating, because even though it's probably meant to introduce a certain amount of real-life unpredictability to the trajectory of the ball that doesn't happen on an ideal "perfect" table, there's something about it that doesn't feel realistic either. But with some practice it's manageable to deal with most of the time. I do find the table as a whole a pretty fun and interesting one, so there's some incentive for me to put up with the funny loop behavior.
