I haven't watched much Akibaranger because it's not really my style. It's one of those adult humor Otaku kind of shows which is certainly popular among adult fans, but not really to my taste. You may like it though, and it's a really short series so not too taxing.
I highly recommend Gokaiger, the space pirate show. Some people don't like the attitudes of the main Rangers, but if you can tolerate them, the show is truly a sight to behold with appearances by every Ranger in history. Don't worry about not having watched older Toku shows, when I started Gokaiger I had only watched two other Super Sentai shows and I loved it immensely. It's a great introduction to Super Sentai as you learn about all the past teams.
Decade...hmm...I really don't like that one. It's one of those dark, brooding, overly convoluted type of shows. It suits some people, but I really can't stand it.
So any ideas what you would like to try? Maybe a Super Sentai series?
