It is said to be safe if you don't dry burn coils, but yeah, with a dripper and an accidental dry hit? That might give off enough "byproduct" to not be so safe, generally. Since SS wire is generally considered safer in TC vaping and can withstand higher heat without causing problems, well, I'd probably start with that unless you are dead set to try and use it for flavor or something.
With that said, it's kind of been noted on another thread, that for overall safety, dry burning SS is less safe than cleaning it with a toothbrush or other scrubby item, then generally pulsing it at low wattage just to make sure everything is glowing evenly and etc. I think the consensus generally is that overheating ANY metal is worse than NOT overheating it. SS does offer several advantages though, it can be run in wattage or temp mode safely, and it's fairly easy to use. I use it in all my coilbuilds.
Is there a reason you want to try titanium in particular? All safety is relative, but it's generally considered that titanium and nickel are the least safe wires to use in TC, although I think if you do your due diligence and whatnot, you should be able to determine what wire is best for YOU. With that said, a lot of the research (not the dry burning research, that seems to be a bit more solid as far as "don't do it" some of it is still in the rather speculative stage. I mean, many things give off undesirable byproducts (think, some plastic) but yet plastic is used all the time, by many people, and they aren't dropping dead over it.
I wouldn't definitively try to say what is safest to any one person since I just feel I don't know enough about it (including research) but unless you HATE ss wire, that's generally considered safer.
