Ok here is my little shakedown....
Bits...
Fast out of the box
can be modded to be even faster
many many hop ups
many many bodies
great handeling(even with rare earth magnet).
many varieties to choose from(buses, anime cartoons....etc)
Where are the ferraris?....and the lamborgini's...?
Easier to find because of the so called "secretness" of them
Parents would rather spend 20 bucks than 40 :-/
Speed mods are easier
Easily finds 20$ miicrosizers at target 2...but parents dont reallt know this..
Zips........
Slow out of the box
can be modded to be faster but not comparable to a bit..
some hop ups and still arnt that great
ok bodies
great handeling
not many varieties(spongbob?........thornberry's...?!)
No skylines?!
20 bucks=good price
Kids love spongebob(hey, he can be funny...
)
need "not so easy" mods to make them as fast as a bit.
waiting lists......
