Anything by Yoshiyuki Tomino as long as it was before '85 is good. Everything else is garbage, especially if it was by Takahashi Ryosuke or made after 1988.

Brave series of your choice, though I would recommend J-Decker

I would also suggest you check out some /m/anga, like:
Robot Keiji
Kikaider
Getter Robo Saga
Babel II
Mars
And some Shirow (Dominion, Ghost in the Shell)

Try any show you think is interesting and never listen to the anons that say x show is garbage because its better to see for yourself whether the it fits your taste or not rather than bandwagoning off of some random fucker's opinions.
you will either never get to see a show you could've potentially liked or feel like a huge dumbass for liking a show that you hated without watching it in the first place.
Don't fall for the same problem that almost everyone in this board suffers through

This is a good way to find what kind of mecha you like. If you want some newer stuff, Big O, Escaflowne, Tiger & Bunny and Full Metal Panic offer a different variety of mecha, although they are hardly iconic. The ones that anon listed are pretty much staples and show you the core of mecha.

It will admit it probably needs some Mazinger, but I thought it best not to recommend too much at once.
