About Tamiya 502x

[taomo]

Hi,
I want to buy a new car, I love Tamiya brand but I readed some bad things about the 502x (easy to break the shock tower, slots in the diff joints are too large -dust easy enter the gearbox-, etc.). I can't decide if 502x it's the best choice for me (run "outdoor") or better the ae b44.1 which it is very similar design. Which one is harder to break?

What's your opinion?
thanks
