To get the most kills skill, ambition, and a solid internet connection will help the most, along with a decent build lol. I prefer to run a Void setup on my Titan, however I run an Ammit with Incandescent on my Dawnblade Warlock along with aspects and fragments that coincide and benefit from the ignitions/Scorch/etc. It does very well and is plenty of fun, however I'm not sure if it is as good as taking advantage of the current void artifact mods and running a decent void weapon (Gnawing Hunger, Funnel Web, Heroes Burden, Wavesplitter, etc). Maybe someone who's crunched the numbers will come along with a definitive answer but TBH I'd just try both and see which you prefer. 🍻
