Zombieland Saga OP - Adabana Necromancy, cute zombie girls and regular girls too, i have no idea what i watched, but it gave me goosebumps.
Mob Psycho 100 II OP - 99.9, i mean, sure, Fire Force has a nun and a fox girl, some fight scenes and cool music, but Mob Psycho wins due to its better animation and (imo) you can see the characters more clearly.
Ramen Fighter Miki OP - Wild Spice, i liked the music, that's it.
The Melancholy of Haruhi Suzumiya Season 2 OP - Super Driver , HOLY SHIT, I HAVE NO IDEA WHAT THIS IS BUT I WANT TO WATCH IT, added to the list.
Let's see, it all comes down to the music, since i like both openings animation. 2000's Rock vs 80's(?) synth sounds, it is actually very hard since i like both soundtracks but i'll give my vote to
Slam Dunk OP1 - Kimi ga Suki da to Sakebitai. (As a side note, protagonist looks like a total chad, i hope i can watch this anime one day, i've never been interested in a sports anime before)
Dragon Ball OP - Makafushigi Adventure (Latino), even though i never watched more than 5 DB episodes in my life, my pride as a spanish speaker tells me to vote for this.
One Punch Man OP - THE HERO !! Shameless self vote.
