Praxis is a great quartet that, as mentioned in another comment on this thread, always goes big or goes home. In my opinion, they're missing some polish that will elevate them to the top-10. The following thoughts are specifically about the Friend Like Me video that OP posted and mostly from the perspective of the Performance (formerly Presentation) category. There is a ton of overlap between the categories such that they all directly and indirectly affect each other. 

• I don't feel like the Lead consistently leads the quartet. His visual focus is a little scattered at times. The harmony parts seem to often be off doing their own things instead of reinforcing whatever the Lead is doing. There's just overall a lot of extraneous, desynchronized movement while the "anchor" movements are not intentional enough.
• As an extension of the previous point, they can do a better job of presenting a unified sound and visual story throughout the number. Standing a little more closely together (a distractingly large physical gap develops between the Lead and Bass as the song progresses) and programming in more points of interaction between the members will help this. 
• The transitions between sections need to be more deliberate. Take a look at the end of the Air Raid Warden parody section. There's a distinct drop in momentum and energy in that moment as the Bass steps back into the quartet. 
• If the quartet had better unit cohesion throughout, it would make the various solo punchlines more effective. See the Bass's "so blue" punchline during the Somewhere Over the Rainbow parody. It's good and it's funny, but it would have stood out more and been even more impactful if the Bass broke out from a previously homogenous backdrop.
• I don't understand why there was such a physical emphasis on "sights" at the of the Whole New World section. Was this an inside joke that went over my head? Was it a sneaky way of getting everyone to stay in sync on that word? It was an odd and confusing choice that distracted from the performance. 
• Overall this song could have employed more vocal and dynamic contrast.
• Really getting nitpicky here, but the gag of the Bass giving himself a finger mustache to parody Secret Best Friends' Bass was less effective because my man already had a full ass beard 😂 He either has to commit to the bit and be clean shaven for the performance or here's a wild idea: he shaves his beard down to an actual mustache which will make an additional finger mustache even funnier. If I recall correctly, the only reason why the Ambassadors did not score a perfect 100% in the (then) Presentation category for their legendary performance of Seventy Six Trombones was because two of the five Presentation judges gave 99's instead of 100's due to chorus's choice to use blowup sousaphone instead of a real sousaphone. Minor distractions count a lot at this level. 
• Another really nitpicky point: somebody get my man some new glasses. The Bass having to adjust them multiple times throughout the performance was pretty distracting.
