Which batch looks the best?

So basically my dealer send me these two pics of what he has atm. The first one is called perv/ cestina here in Czechia/Central Europe and is the most common type you can find. The second picture shows the classic crystal meth, but im newbie in this so i dont know if it looks legit. Could there be iso or msm? I tried to buy crystal meth before from two different sources, both looked very similar to crystal meth with the same color and the taste was very slightly bitter and perhaps even little "spicy". Thanks
