meth vs cat ?

[genaro]

this quote is from the Methcathinone FAQs (from erowid): "methcathinone induces mania more so than methamphetamine, but psychosis much less. The initial dose produced some paranoia, but subsequent doses did not make this worse (?) and in fact seemed to lessen it. This is definitly a drug for goofing off, unlike methamphetamine which makes one 'serious'.

So...

If anyone had the opportunity to try both Methamphetamine and Methcathinone, how do these compare ?

meaning duration, energy, ophoria & well beeing, anxiety/nervousness & psychosis risk, side effects & toxicity, hangover, addiction? Which one do you think to be the best and why?
