Outside of a couple of episodes of Gavan I have not, but I'm gonna watch Jiraiya.

Metalder is pretty great.

Good luck. Jiraiya is an unusual but cool show with a super-catchy theme. In general, Metal Heroes is definitely worth watching. Another thing is that the first few shows are somewhat monotonous. It is also worth remembering that they were announced as a franchise after the fact, so in essence these are just different tokussu shows that occupied the air before the return of KR.

I've seen a few of them. Watched Janperson earlier this year and really loved it!

I actually started Jiraiya sometime ago, funnily enough, and the show is already off to a pretty good start so far. Oh, and Metalder plus Janperson are great shows that are definitely worth checking out.

I've watched a few episodes of the Space Sheriff shows but I've seen most of Metalder. Metalder is really good.

I've seen 6 installments and am currently near the end of my 7th, Solbrain, which I'm enjoying. Good choice on Jiraiya, this is an awesome take on the ninja genre with a unique premise. Mostly comedic, but has some dramatic moments as well. Other than that, I agree with the recommendations for Janperson and will add my own for Jiban, my personal favorite so far.

I'm trying, but none of them really capture me. I started Juuko B-Fighter, but it's just not clicking.
