For MPG absolutely. Otherwise, not better than 3FE or 1FZ.
Better MPG. More power. Less weight. No head gasket issues. High mileage examples becoming more common with time passing.
People defending the old engines is funny. Reminds me of the die hard 23r/re guys. I owned several. All of them needed ongoing adjustments and rebuilds. 3RZ worlds better for reliability, power and hassle free.
People will make the same claims on the current Toyota motors when they are no longer being sold 15-20 years from now. Or you could enjoy it now! Just sayin...
