Honestly, I don't know how one would go about making a guide based on cool factor, since cool is such a subjective perception.
I think swords are really cool. Others think axes are cool. Some poor benighted souls think double bladed suicide swords are cool.
Some people think having a spell for every occasion is cool. Other people think that calling on otherworldly eldritch powers to aid them at the peril of their very soul is cool.
I can talk about how, as a cat person, the saber tooth tiger is an awesome wild shape to turn into (and lamenting how much more powerful the bear form is), but to a bear guy, the bear form both way cooler, and mechanically more effective.
None of these people are wrong (except the double sword guy), but it would be hard to make a guide for all of them.
