1/500 once VS. 1/100 5 times?

I'm curious on your guy's perspective on this.

Take Venator bow for example: should this be a 1/500 single drop? Or is getting a 1/100 5 times better?

(Totally asking because I got spooned 4 shards, and now I'm at 432 kc and it feels a little bad that I'm not getting super spooned the bow like I anticipated)
