Well, the proline MT is 1/10, smaller scale. Keep that in mind. Like comparing the stampede to the t-maxx. Also, it has pillow ball suspension which can be a nuisance with the balls ripping through them on rough landings.
The CEN is big, but a fairly proven rig with plenty of ebay parts support.
The Arrma outcast appears to be relatively low to the ground for a MT. But is a far more simplistic machine to work on vs the CEN and is also 1/8th scale which runs a larger motor and capable of supporting 6S. However, pillow ball in the front as well and the front arms look somewhat fragile. Maybe Arrma plastic is soft and flexible, I've never had one.
The Tekno MT410 is also 1/10th, but looks like a fairly well built rig.
I can say, having a brushless revo, savage flux HP (non-XL length) and a traxxas stampede 4x4 vxl that the revo and savage get through places that the stampede can't due to it's size. Also, the motor/esc/drivetrain and suspension aren't nearly as stout on the 1/10th rig.
That's not to say the stampede isn't fun, it is. I run all 3 about the same amount. In fact, I run the stampede more than the revo or savage as I tend to always take it out with the revo or the savage when I go out, but I rarely take both the savage and revo out at the same time. Too annoying to carry down 3 flights of stairs. The savage and stampede or revo and stampede fit ok in my hauler bag, but the revo and savage don't fit well together.
