imo, Red Swan (AOT) for the opening, and Lost in Paradise (JJK) & Shissou (OHSHC) for the endings
i feel like Red Swan is the underrated opening out of all the AOT openings, since the rest of them are so hype and memorable. idk, i always cry while listening to Red Swan and i've never skipped it when it was used
Lost in Paradise just got me so hype and the animation that went with it was so cool, i never skipped it either. it's also an unironically good song that i listen to casually
and the guitar riff in OHSHC always brings a tear to my eye, with the added bonus that it's very nostalgic for me
