How we mark a row

A tick marks the better of the two only where one is plainly better for anyone: advertised pay, typical pay on live jobs, how easy it is to get in, steady work, the payout record and schedule, and where it hires. Pay rows need a gap of at least 10%, and the live-jobs rate needs 5+ priced listings on both sides (otherwise it's under "Can't compare yet"). The advertised-pay tick goes to the higher advertised top; a single live listing above it is shown as context, not counted. There's no overall score: a better payout record matters more than a payout day, so weigh the rows that matter to you.

"Hires worldwide" and "Open to India" are marked on listings posted in the last 4 weeks, so a pile of months-old posts can't win them. Payout method, time to apply, open jobs, recent posts and red flags are context, never a win. A count of red flags mostly shows how much has been written about a platform, so read the flags themselves below.
