there are many 8 scale brands. I like always like mugen n losi. losi very nimble. I have not broke anything. jump very natural. mugen very solid with very little slop and parts quality are top notch.
by the way if you are "new hand" you should consider Rtr. bcs buulding a 8 scale buggy takes skill. no joke. I just checksd amain. your budget around 4k. you can only choose rc8 or sepent rtr. plug amd play. learn how to drive n set up a car. sounds like off topic . 8 scale to new hands is really too much headache. but once you get it mastered; fun.
losi and mugen . I personally think better. losi 8 scale buggy has long history so does mugen. I can say the brands that you mention for their 8 sclae history is 後輩
