Let's go this route: An army of guardians vs. the UNSCs Spartan population. Spartans have superior technology, based off of what we know/have seen. Their armor is better as we should all know, and reflexes vastly superior. Spartans are serious and mission-oriented, and will always put their tasks before themselves. They are masters of stealth and extreme pressure problem solving, and their improvisation skill is outstanding. A Spartan's strength is greater, and is nearly inexhaustible, which is a major asset. Guardians have "space magic" at their disposal. Their super abilities are very powerful, yet limited. Guardians are not trained soldiers, and therefore, are far less disciplined. Their weapons are powerful, yet are limited to on-ground warfare, having no artillery or weaponized ships. Their major asset is their ghosts. Serving as an AI with resurrecting capabilities, they are easily the ultimate companion. However, these also serve as a crutch. Guardians are reckless, knowing they can be revived in most situations, at ease. In one-on-one combat, a spartan has all the advantages, being in a 1,000 pound suit of titanium, acting as a second skin that responds to their every thought with lightning quick speed and precision. Blink/glide could be seen as advantageous, however, they can be easily countered by a spartan, due to the inferior speed and flight time. Blink is the best bet, though only warlocks and hunters, who are lacking in armor, are granted with said ability. These arguments will continue for as long as these games exist, but if you can't bring yourself to look into facts, rather than opinions, you won't realize which is truly superior.
