Fairly sure, definitely oak flecks on the lower one. Hickory has smooth grain, but looking at an off-cut end grain would be a sure tell.
The second I'm confident is white oak ("almost" quartersawn).
Not sure why I had the first initially picked as hickory. I'll have to see what pieces I have left to view the end grain. Will post if I can find some as now I'm curious what to look for in the end grain.
