1/8 truggy or crt.5 / mayhem st? What would work best?

[R00ST]

The length of the mayhem st pro is 19.4 and the width is 16.5

The crt.5 is 14 length / 11 width

The lightning 10 ST is 15.9 length/ 12.6 width.

The rustler is 16.7 length / 12.6 width
My rustler is probably about 17.5 length and 14+ width.

For comparison an ofna 1/8 buggy I looked up (hyper 8.5) shows up as 18 length / 12 wide
