Xtol is very low toxicity, it's full speed, even having 1/3 stop more in the shadows than D-76. Fine grain if you standarize also for lower formats, and kodak says it's sharper (better perhaps for small formats).
With xtol you have to mix 5L, better with distilled water for long shelf life.
Me, I use Xtol 1:1, I would use HC-110 only if wanting a more pronounced toe/shoulder.
