I've used both Tung and Blo many times and really don't have a preference.
Tung- gives a nice clear somewhat hard finish. It dries fairly fast.
BLO- dries fairly slowly. May take a dozen or more applications. turns the wood a reddish color, isn't very water resistant. It smells good. When I have a BLO finished stock I apply a slurry of Beeswax/lemon oil over the top (can't rememebr the brand name of the stuff, I'll have to look).
