Sigelei #8 and #13a are good and look better than the China GG with wider diameter gennies like the Aga-T's. China GG looks good with my Chid and Chobra and Igo-L. Personally, I prefer the look of the Sigelei, brushed SS rather than chrome of the chi chi. The quality and the vapes are about the same to me, and they all take 18650's and 18350's.
