If it were not for the non/consensual aspect of the nudist option, that would be my choice - although both are appealing.

The model option is WORK. And it can be painful. A two and a hslfor three hour pose will inevitably hurt. I’ve seen models flame out with only minutes left in a long reclining pose as their body finally won out over their mind. Another had to abandon a standing pose after 40 minutes. I’ve been in a simple three hour pose with the head looking to the sky and skyward when the neck muscles were still sore two days later. If the intent of the question is to model for hours per day, every day, the grueling toll would probably be more than most could handle.
