Ti and quartz are comparable. Ti can get hotter and lose a little flavor with the dab, but it holds heat a little longer. As long as you avoid hearing it super hot with a propane torch and oxidizing it, you should be safe from inhaling Ti oxide which is what is claimed to be found in higher levels in some people. Definitely a hundred times better than glass. Make sure you get a name brand nail tho, there are a lot of cheap low grade ti nails that say "Mfg USA" or "Gr 2", if they say this on the nail it is a cheap Chinese low grade nail and will hardly hold heat and sometimes fuck up your dabs an tate weird...
