Top 5.

1) Zyuranger. I may not like MMPR that much, and I may have never seen Zyuranger, but these suits are just so iconic to any kid who grew up in the US or UK in the 90s.
2) Jetman. My first sentai that hadn't been adapted into Power Rangers and I just mean look at these guys, the suits are just so detailed and ahead of their time, they are awesome.
3) Magiranger. Love the colours, love the details and I really love how they tried something different.
4) Gekiranger. They are just awesome in how unique they feel, it also helps that they were adapted for Jungle Fury, my favourite Power Ranger show.
5) Goseiger. My favourite sentai team, and although I'm not all that hot on their Super Change, there is something about the refined detail and blend of new and old in their base design that I just adore.

Individual.

Time Fire as the Quantum Ranger is my all time favourite Ranger.
The Thunder Rangers - they were just so damn cool looking.
The Psycho Rangers - one of the coolest concepts in Power Rangers history, how come they've only ever been done once? They are just so, so, so cool looking. Blending classic Ranger design with nightmare monsters.
