KDX-250 vs TS-200

I'm thinking of buying one of two old shitters I've seen advertised. The first is a '92 KDX-250 and the alternative is a Suzuki '88 TS-200. Does anyone have any knowledge on either bike that would help me decide on which is best to buy for steady trails riding ?? Or is it just a case of they're both old shitters so just go with the kwaka.
