>>6121297Here's what I can tell you:
Bits tell you exactly how much the talent is actually getting, unlike superchat which have a Youtube cut, for every bit the talent gets $0.01 USD, this is regardless of region, no ARS can be used to bypass this, of course a single bit is slightly more expensive but still, fairly convenient for the talents to get a system that can't be bypassed
Subs also are the same price regardless of region, and subs can be mass gifted on Twitch, which can result in quite the significant difference when compared to Youtube's members
