It's really tough to be un-biased and judge only on suit designs, but here's my attempt:

Teams:

5.) Shinkenger- Though this may sound like a rant, the slickness and complexity of their helmet designs by themselves truly do put them in this spot. The only issues I have with the designs are the way Shinken Yellow's helmet design looks and Shinken Pink's design in terms of theme, though I don't think there's a way for Shinken Yellow's design to change to make it look better since the kanji for earth just happens to look like that. The kanji they used for Shinken Pink's helmet design looks like it should belong to the leader of the team because of the large impact that Chinese (and possibly Japanese) mythology has with that character. Also thematically, I feel that Shinken Pink should have been Shinken White and have the character for metal (金) so that the team would have a "Five Elements" theme, making it even more akin to Japanese culture. Nevertheless, the team's theme influenced suit designs are solid enough for it to be on this list.

4.) Megaranger- This one's probably biased since both In Space and Megaranger are respectively in my top 3 favorite PR and Sentai series, but their helmet designs are really nice, and the five colored squares on their chests really gives the feeling that they belong together in a team.

3.) Carranger- Their helmet designs by themselves would easily take the #5 spot, but their textured suit designs along with that make them stand out even more than Shinkenger's and Megaranger's designs in my opinion.

2.) Gokaiger- The suit designs for this one really serves its theme well. The shape of the helmets and the jacket-like design makes this team really stand out.

1.) Liveman- A simple concept that is done exceptionally well. There's something about the aesthetic look of the combination of helmet and suit designs that make this team look more appealing than other animal-themed sentai like Sun Vulcan, Gaoranger, and Gekiranger. The large animal outline insignia placed at the center of their chests combined with the well-sculpted, cartoon-like look of the helmets makes the team look so nice and exceptionally detailed. I never understood why Yellow Lion's animal insignia looks so different from the others though...

Honorable Mentions ('cause I'm so indecisive):

Goranger, Dynaman, Flashman, Turboranger, Fiveman, Jetman, GogoV, Gaoranger, Hurricanger, Abaranger


Individual:

5.) Shinken Blue- I've always loved the way the Chinese character for "water" looked, and seeing that on Shinken Blue's helmet made him an instant favorite for me.

4.) Abare Killer- His red visor on his otherwise contrasting black and white spiked suit design gives him the look of a fierce predator. It's difficult not to like the suit's design.

3.) King Ranger- The single gold outline of the Chinese character for "king" on his otherwise plain helmet is a design concept that sounds terrible, but is just executed so exceptionally well. That combined with the curved design of the armor on his chest and the additional details on his suit as well as the contrasting black and gold colors makes him really eye-catching and appealing.

2.) Red Falcon- The best design from the overall best team. Need I say more?

1.) Battle Japan- The entire Battle Fever team would have been in my top 5 teams for this list if not for Miss America's and Battle Cossack's odd aesthetics. Battle Japan is one character whom I feel is very underrated because his suit design is really slick and iconic in Super Sentai, kind of like how Captain America is for Marvel's American fans. When comparing the actual Battle Fever J suits to Itahashi's and Kaida's original designs, Battle Japan's suit is the only one that I think actually looks better in its final form than the in original design.
