Well, I personally think everyone should finish up the entire show, or at least most of it, before they can have a final opinion on it. So I personally recommend to finish Kabuto.
Indeed, Kabuto's story is messier, compared to most of the other Heisei Riders. And that definitely makes it a weaker season. Though it's not as bad as Decade. Not NEARLY as bad. :loltongue:
As for Tendou... if you don't like him, then you're more than likely to not enjoy Kabuto at all. Fans are divided on how they feel about Kabuto. Some fans think he's a really awesome character. While others think he's a despicable jerk, that's hard to find likable.
I personally think Tendou is an okay character. Yeah, he's an arrogant jerk. But I give him credit, because he acts the way he does in order to help the people around him become happier and better people. Where as Tsukasa (Decade) was just a jerk just for the heck of it. To be honest, I think I just find Tendou more intriguing rather than directly liking him. And that credit mostly goes to the character, Kagami. Kagami imo is a great character, whom I can easily relate to. He's like the "normal" person in the show. The story is told from his point of view, and we get a taste of what it's like, being with Tendou, who is a character that's pretty much perfect to the point where you could say it's unbelievable. A lot of the times, you just want to see how Tendou works his way out of certain things. And what's also great is the he actually loses sometimes, which gives a sense of realism. Plus, great actors also support the cast.
That's my view on Tendou. And why I was able to watch through Kabuto. Kabuto had a lot of fun elements. It had an entertaining cast of characters. And an awesome battle system (Clock Up). The designs were great too. The story was messy, but I felt like it was a perfect example of what to do and what not to do in a Rider show. So overall, while Kabuto may not be the best, I think it's still worth watching. As it has plenty of gems in it that really shouldn't be missed imo.
