Blade. Blade had a great, yet bittersweet ending

Blade, easily, has one of the better endings in KR.
OOO also has a rather nice ending.

...Mhmm, yep. Those are the series with the better endings. Fourze and Double were adequate, Gaim's was...Okay, and the rest tend to lean on the subpar category (Well, of those that I've seen)

Yeah Blade had a great ending, same with OOO, I would also put in Ryuki but then I am super biased to Ryuki having a good ending so that is just my opinion.

I am surprised in my reflections that I can't find an ending that I found flawed to some degree of severly lacking, although I have not watched much of the showa era so I have no idea those hold up.

Agito has a pretty fantastic ending. You get an unusual final confrontation and decision made by the enemy after which you're treated to a look into what the characters are doing with their lives.

Also thoroughly enjoyed Blade's ending, it's one of the very few I feel lives up to the original idea of Kamen Rider as the "lonely" figure who can never actually be with people. That final scene in the park with the bench is pretty great, I don't think it'll ever lose its impact on me.

Also loved Gaim's ending. Sometimes you have to sit back and remember Kouta being a normal guy at the start of the show with normal issues. Even as he gets his powers, he has no idea how irrevocably altered his life's going to be in around a year.

Stronger and Black also have fine endings. Stronger was, at the time, the end of Kamen Rider, so to see every Rider coming together was great. It had a real sense of finality. Black's ending I loved because, like Blade, it shows you just how far a hero has to go despite the fact he's going to end up alone.

Blade. It made me didn't really care much about Kenzaki (because Tachibana and Hajime is just too awesome, and Mutsuki has a good arc) into respecting the shit outta that guy.

Usually in the "Hero sacrificing himself" trope it'll always ends with the hero dying, but not Kenzaki, he still lives, but in turn sacrificed his personal life just to keep the world safe and so that Hajime can live.

Is Kamen Rider was a better show than Super Sentai?

I would say probably because Kamen Rider don't have an unnecessary giant robot fight which Super Sentai keep doing that for the sake of the children!

Kamen Rider often focus on each different character than Super Sentai. Super Sentai always focus on Red Ranger no matter what!

Even they got a human villain! Old Super Sentai used to have a human villains but not anymore so far because most of recent Sentai often relay on Monster Villains because I don't know! I bet Parents don't want their sons drooling on a female human villain! I guess!

And they have a story arc compare to Super Sentai which they always used bunch of filler episodes!

I think Kamen Rider has more potential to tell a good story than Super Sentai because there are less things they need to show us in order to sell toys. In Kamen Rider, the collectible gimmicks and various forms mostly apply to the fights and are easy to work around. In Sentai, having a giant robot fight every episode severely limits what you can do. Also, it's easier to work with 1 main character and a cast of side characters than it is to try to balance 5 main characters.

tl;dr I think Kamen Rider is indeed better due to the nature of the two shows.

Black has a fantastic ending. It's actually kind of a downer, but it fits the tragic nature of the show to end with Kotaro sitting alone in the coffee shop, reflecting on all he's fought for and lost. Black won in the end, but it was pyrrhic victory and the show doesn't let your forget it for a second.

Blade is the other series with a classic ending. Again, it's a mixture of triumph and tragedy that serves as a great finale for both the main characters and the story. One of the big reasons why I hold Kenzaki in such high esteem is because of the sacrifice he makes at the end.

I like the conpect of Kamen Rider better. I like the idea of a solo hero fighting instead of one team of characters. Even as a kid, I like solo heroes better since I watch Spider-Man on Fox Kids over X-Men (I watch X-Men but not as much). Kamen Rider also tend to have a more serious storyline and tone for the most part compare to Super Sentai.

I doubt that's the reason. I think it may be easier to have suit actors than having human actors.

Which Kamen Rider or Super Sentai show that you totally regret of watching from first episode to finale?

For Kamen Rider- I'm regret of watching Wizard 1 to 53 because it was rubbish and boring! to this day, I'm still refuse to rewatch Wizard!

For Super Sentai- I'm regret of watching Kyoryuger 1 to 48 because I felt I was watching a Red Ranger show than Super Sentai! This Red Ranger was so Marty Sue! Most of his teammate were treated as his sidekick! I think Riki Sanjo wasn't a Super Sentai guy. Heck! I even skipped Ninninger after 6th episode because I just couldn't stand this obnoxious red ranger who scream for no freaking reason!
