Unpopular opinions about the Super Smash Bros series.

I'll try it later to see if I can actually beat it on Hard, as it is the only event match which I haven't gotten the reward from.

I prefer Port Town Aero Dive over Melee's Mute City.
 
I was about to question your judgment of everything
 
Another unpopular(?) opinion of mine is that I don't dislike the fact that there are 6 versions of the Jungle Hijinx theme in SSB4 for Wii U.

These are my favorite costumes for the characters I use the most:

One of the best things to do in an 8-player Smash is to power up a hothead, wait for a CPU to pick it up and throw it and then reflect back at them. Then you can watch the hothead send them flying for a one-hit KO or the hothead destroying their shield in one hit. The stage used is preferrably Final Destination or an Ω stage with a similar structure to it like 75m.
 
Brawl has three things over the other games in the series:

The best "No Contest" screen.

The best perfect shield sound effect.

The best sound effect for DK's Hand Slap.
 
Honestly it's very hard to tell if your opinions are unpopular because they're typically small details, which I don't commonly hear people talk about
