I think they're not really too great unless on a stream or something ; o; because the artist could be charging like 758200284747$ per hour and then take like 6 hours for something that's
a)Not really worth the butt ton of monies :I
or
b)Probably could have taken an hour tops if the artist wasn't dawdling >_>

And there's really no way to test if they're not doing it on purpose unless you're watching and I have trust issues OTL

I agree, artists can be very untrue about that. it's very nice to see both sides of the coin!
