Specifically for modeling and rendering, NVIDIA. For starters, more engines are supported on it (such as Iray), and the cards are more efficient.

so what benefits does AMD offer if any? I've seen comments about better multitasking but I've never had issues alt tabbing from games and playing youtube, browsing etc etc etc simultaneously

Mainly efficiency (though, in fairness to AMD, price/value in the midrange is their strong suit).
