Really just look at the simplicity of the two. Titans can press a button, get an easy kill. Hunters press a button, become a sitting duck for a while, charge headfirst into the fray, an risk getting killed. It physically takes more effort to use a blade dancer, but that's not really the point. There are two factors in the "skill" associated with supers: potential and vulnerability. Fist of Havoc takes little effort to use, meaning you can just pop it out in a moments notice without really worrying about being killed in the process, on the other hand, once you activate it, that's it. Looking at just the base of both supers (disregarding the modifiers in the skill trees) you clearly see that you have more control, and therefore, more potential with the blade dancer, however, a blade dancer can be brought down pretty quickly if the other team has half a brain to shoot at you. In simpler terms, with more potential, comes more vulnerability. This ratio is basically bungie's way of evening out the supers, so truly, Fist of Havoc takes less skill, but that's really irrelevant for the competitive gamers, because most people should know generally when to use supers, and how they can be effective. To sum up (I know this is a lot) all that really matters is your play style; if you want to be a little more risky, but more effective, choose the bladedancer, if you want an easy to use, but restrictive super, use the titan. When it all comes down to it though, the gameplay is more focused on guns anyways, you get significantly more kills with a shotgun than with a super. So let's stop dwelling on the slight imperfections in balance of the smaller aspects of crucible.
