User blog comment:Legionwrex/Spectre vs Spartan II/@comment-2256917-20110106221131

Spart's original post is right on about the uniformity of the Spartan IIs, in contrast to the Spectres. But we can restrict ourselves to Shepard and in-game encountered Spectres. -- On the surface, a Soldier-Shepard Spectre seems very comparable to, say, the Master Chief (broad weapons and hand-to-hand proficiency, vehicular use, courage), even if the Chief (in armor) were heavier and a little taller. In fact, ME2 Shepard is also enhanced with cybernetics (like the Spartan II). Both are assumed to be hardened soldiers, and neither show problems using new weapons (at least after ME2). Circumstantially and/or well-used, any weapon can take down either of them or can be avoided. On the other hand, the possibility of biotics seems to give a advantage. But a non-biotic Soldier-Shep Spectre can take down such as Vasir and Saren. So why couldn't the Master Chief (e.g.) do the same? So even biotics can't be decisive, unless we assume that, say, a Vanguard or Adept Shep is necessarily superior to the Soldier class. Of course, an Engineer Spectre could have that pesky combat drone...
