The only one I can vote on and the easiest one as well - it's Zyuohger.

The best Red I have ever seen, not a stupid loudmouth but a reserved, tactical leader who deeply cares about his team. Which was also great, every single member had something unique to add so the whole experience actually felt like a group that was more than just the sum of its parts.

Plus - the best sixth Ranger I have ever seen to boot. Misao is introduced as a big bad Ranger but once rescued he becomes such a unique figure that seemingly does not fit within the dynamic of the group but strangely enough that incompatibility is exactly what fuses them together. He has a fantastic character arc and I will never forget the scene where he rushes out of the hospital to stand by his friends.

Yeah the villains are lackluster, the overall story only scratches the surface of what's possible but still - to this day this is the best Sentai show I've seen, I actually miss it too, so I will absolutely rewatch it at some point.
