Yes, white oak acorns have less tannins which makes them sweeter. Their acorns also mature in 1 year while red oaks take 2 years to mature. That is why some years where there is a late frost, the reds will drop acorns as their partially mature acorns weren't affected by the frost where as the white oak catkins were frost killed. However, the following year, the reds won't produce but the whites may have a bumper crop. That is why it is important if you are managing timber for deer and other wildlife to try to diversify and make sure you have oaks from both families. Red oaks can produce acorns every year, they just require 2 years for their acorns to mature.
Sawtooth oak, Quercus acutissima a species from Korea and China, it is a member of neither the white nor red oak family but rather a family known as the Cerris oaks which have no members native to North America. The sawtooth oak produces acorns rather fast, is fast growing, hardy and the deer and turkeys love the acorns. I would suspect the sawtooth oak would do quite well is most areas of eastern Texas. Pennsylvania is about as far north as they can be expected to reliably do well. Their leaves look a lot like a chestnut tree's leaves.
