Hetalia rated as boyfriends best to worst:
Germany-hes doting, but still serious. A good communicator. His SO lucked out. He’s not good at romance, but he tries. And he gets better. Not to mention he’s incredibly loyal to the one who holds his heart.
Japan: If you ever get to the stage with Kiki, he’s a great partner. Level headed and responsible, though he isn’t to keen on gift giving and will often just get stuff you need.
Prussia: listen once y’all get past his insecurities and build a solid relationship, he is a dream boyfriend. Is prone to feelings of unworthiness though, so he needs a partner that can reassure him.
Lovino: Once you get over the first couple of months, and he finally trusts you, he’s a Perfect Partner™️. He’s doting, romantic, and he can cook!! Anything for his SO! He, like Gil, is prone to insecurity though. So he needs reassurance from his partner.
China: he has plenty of life experience and he’s a great communicator. He’s also down to earth and loyal to his partner. He’s had plenty of time and learned communication is key to successful endeavors. The only downfall is he fails in the romance category. He makes up for it by providing an incredibly healthy and stable environment for his partner.
America: he can be immature and that can take a toll on a partner. But he’s incredibly loyal, and does his best to keep the romance alive. Not all of his plans are well executed, but he always puts in his best effort. He can tend to be clingy, while also not understanding a clingy partner. But once he’s in it, he’s committed. Very doting.
Sweden: he’s upfront and honest, however is also a bit of a cynic. This can make dating him difficult. He’s also not great at talking about his feelings, and doesn’t do well with romance. But he does communicate with his partner well after enough time has passed and he’s settled into the role.
England: more mature than America, but arguably more emotionally constipated. Arthur has a habit of sabotaging his own relationships. And even though he’s in love, he struggles to verbalize his feelings. Often leaving his partner at a loss.
France: He loves to love, and he loves to be loved. He’s a doting partner and full of romance. However his relationships tend to be the flash in a pan type, and he gets bored before inevitably moving on to someone new. It’s fun while it lasts.
Switzerland: he’s just not a great bf okay?? He’s crotchety, and he won’t so much as buy you a chocolate. Not that money is everything but when there isn’t give and take in a relationship it leaves one party feeling used. He also doesn’t make his SO feel particularly wanted.
Italy: He’s charming and sweet but good fkn lord does this man cheat. It’s like lovino got all the loyal genes and Italy was left with all of Grandpa Rome’s hoe genetics. Do not date.
Spain: listen. Tony is a hoe. Baby he’s lying to you, leave that man. You know what Spain rhymes with? Pain. Yeah I said it.
Greece: He’s a lazy hoe. At least Tony puts in some effort and romance.
I like it cuz it's true
