But to you nothing is as good as Dairanger so that opinion is a bit biased

Jetman is one of the most solid early Showa sentais out there. The design influences changed drastically between it and Zyuranger sure, but Jetman is still a very compelling and excellent show. Aside from more extravagant mecha and a 6th warrior I don't see much that sets Dairanger apart from Jetman. Don't forget that they do both have giant middle finger endings A repetitive cycle of battles that never end for Dairanger and Gai's random death in the last episode for Jetman. If anything there on the same level quality wise, though I personally thought Jetman was a better crafted series.
