My ZhanChi is the only one of my two speed cubes that is lubed and tensioned and my FangShi isn't broken in either. But I usually get better times on the FangShi, because my ZhanChi pops sometimes (the FangShi never pops. Even if you try) and because the FangShi is slower, I can look ahead at max TPS and have nearly no pauses during solves. Getting my FangShi actually dropped my average by two seconds and got me sub-20, which I really didn't expect, especially as it's black and white (I've only ever used black cubes before). It's also 2.6mm smaller.I used my DaYan Zanchi this week, Because it's the only one of my two speed cubes that is lubed and tensioned. (my FangShi isn't even broken in yet)

Wow, that was the worst start ever. Don't know how I got a NL sub-14; it didn't feel like a fast solve so I didn't really try at the end, until half way through the H perm I saw it was 11.xy.
