sentai series with the best monsters?

[live jetabare]

Hi; Monsters of the week are trademark enemies in Super sentai; however, which series has the best MOTW?
In my case, I have a big fondness for the GogoV monsters; they really have a scary design, and you have a really feeling that the GogoV fight against hell spawn every week; of course, some monsters have classic animal design (elephant, mole, spider); however, even then, the design is really well done; as a result, the heroes's fights feel even more epic (helped by an awesome soundtrack to boot); and of course, having main villain with a nice design helps too; Zylpheeza, Kobolda and Salamandes's design have also a really demonic vibe; and Dinas, despite being human looking and played by a beautiful actress isn't the least scary of all. A great example is the finale with Zylpheeza and Salamandes's dragon form as final monsters.
And you? which series has your favorite monsters?

Gekiranger - Most of them had some really creative designs for the respective animals that they were modelled after.

Ohranger - I really like how mechanical and colorful the Machine Beast were. Sure, there were goofy ones; but I felt they really had some interesting creativity behind those designs.
