In multiplayer, in which order are replacement effects from different players applied?
The order in which replacement effects are applied to an event is chosen by the player or controller affected. In this case, the event in question is your creature dying, so you choose which replacement effect applies first, and which opponent gets the token.

The specific rule that covers this is rule 616.1:


  If two or more replacement and/or prevention effects are attempting to modify the way an event affects an object or player, the affected object’s controller (or its owner if it has no controller) or the affected player chooses one to apply, following the steps listed below. If two or more players have to make these choices at the same time, choices are made in APNAP order (see rule 101.4).
