The ones involving Hideaki Anno are true gems.

This stack is my fantasy head-canon... how cool would it be if this output were from one single studio? Well, due to the "Gainax Spirit", it almost can be considered one studio... (Not really. But. You know what I'm getting at, right?)

Gainax eventually lost its way, but one ex-employee founded Studio Trigger and carried on the former's legacy. The passion, creativity, skill, and ambiance once found during Gainax's peak seems to have profoundly influenced Studio Trigger's catalogue. This interest stack is a journey through the most notable endeavors of both studios. While the studios are obviously different entities, their characteristics and genetics are remarkably similar. Since "Panty & Stocking" is Gainax's last truly notable project, there is a nearly seamless transition into Trigger's "Kill la Kill" and "Little Witch Academia".

Anime featuring mainly traditionally animated, hand drawn robots made between the year 2000 and 2009. As CGI started being used in anime in this period, some mecha series started shifting towards CGI robots, I think this list would be really helpful.

These are extremely good, high quality mecha anime picked across 5 decades of the medium you can get emotionally invested in, creating a genuine level of immersion to their masterful work. They are meaningful, real life influencing works, with themes that serve as important life lessons, with characters so connectable they might as well be real people, with fully realized concepts and fantasies, with stories worth the gravitas and seriousness they demand. While they might be on different levels in the immersion scale, they're all pieces of art that with their good animation, writing, directing, sound direction, art direction, and theming are well worth a watch even for non-mecha fans.
