short answer: get samples.
medium-ish answer: what i like may be different than what you like. and what you like may be different than what BGingGA likes. we all have different tastes and like different things when it comes to chips. that's what makes this place so interesting and fun, imo. some like flashy designs and some like subdued designs. some like real clay chips (asm, paulson, trk, bcc), some like ceramics, some like plastics (matsui, bud jones, etc.) and some like china clays. some like them all. while it's great that you are asking for so many opinions on all these different types of chips, the only opinion that matters is yours. which is why it's best for you to get samples so you can decide for yourself.
As strange as it is to say, I actually think it's more important to get samples of ceramics than clays. I really love all the clay varieties differently and would never be disappointed with any of them, but there are certain ceramics that I really can't stand.
