heh heh.. interesting..
after reading all these, as a relative newbie, i would just like to say a big THANK YOU to my brudder to got me into
vaping! YOU know who u r man!! and all the fantastic pple i got to know who were so willing to share their knowledge wif me! Y'ALL know who y'all are!! yink yink yink..
having said all this, TS, i feel it is our own responsibility as newbies to do our own research b4 asking others.. the internet is choked full of information. u just need to sieve out what's useful n relevant to u. (GOOGLE man!!) if not, there's nobody else to blame if u kena carrot chopped by someone who's just waiting in line to separate u from yr hard-earned cash. i'm one of them too! dun believe come ask me for advice..
esp. in singapore where many pple justify exorbitant mark-ups by saying, 'i took all e risks bringing it in, YOU try bringing in yrself den.. etc.' now seniors, i'm not pointing any fingers.. i'm guilty of it too! ;P
but how much money is dat 'risk' worth and how much y're willing to pay is very personal.. $500 for a provari mini? (provape sells it for $210 n it's pertually available!).. some consider $350usd for a 2nd hand orion cheap, others do not. (new one is 150euros).. n many other factors come into play when prices r concerned and as y've found out, the z-atty is nvr available from it's original maker.. so? wait for availability or buy higher from classifieds? it's ultimately yr call.
now to answer yr question directly.. having had the good fortune of owning BOTH imeo n genesis styled attys (hahaha, yes i'm boasting now!

- courtesy of all e wonderful brothers in the sg community who poisoned me!!) i think i'm qualified to tell u: BOTH ARE GOOD LAH! both got its fantastic share of followers!! ask any vaper who's been
vaping long enuf.. yr favourite is genesis, but do u also keep a gg full set? why? n vice versa for ody die-hard fans..
so try both! n try alot of mods! alot of attys! spend more money! try different juices! they matter too!! den y'll know what's best for u and u only.
i think dat didn't help much.. =PPP
