Who do you think is the more better hardest boss? Orphan of Kos vs Malenia vs Consort Radahn?

Who do you think is the more better boss? Not in a hardest boss type of way, but in anything else. Like gameplay wise, soundtrack, lore wise, all that type of junk. You can also bring up hardest bosses in other fromsoft games if you would like to, I'd love to hear your reasons why.

If I have to choose, I'll choose Orphan. I'm totally bias because not only BB is my favorite and first fromsoft game I've ever played, but Orphan is the only boss among the three that I ever defeated solo, I literally jumped in joy when I saw that NIGHTMARE SLAIN text on my TV.

Anyways, the reason why I choose Orphan is because has cool lore, a wonderful soundtrack, and a very exhilarating move set. Not only that, I think Orphan's a fair fight as well, he doesn't really have any bullshit moves like Waterfowl or >!Miquella!< blinding my ass every 0.1 seconds.

No hate to these bosses (maybe a little bit of hate haha), I just love Orphan more than them.
