I cant comment on the quality of those two buggies as I have not owned or used either of them, I do however have a Bazooka and can say it is very durable, it is not a high end buggy by any stretch but from what I have seen personally and at the local track they are quite good for the money.

If you can get the car cheaper that is great, 90% of people still buy there parts/hop ups from Plaig as the ebay sellers have little to no support after the purchase.
