I love pigeons too, they are beautiful and comical birds which do not deserve anything like the amount of hate they get. Even feral pigeons have beautiful iridescence on the neck feathers and some other members of the family are amongst the most beautiful birds in my opinion. I also find their calls very soothing to listen to, especially the European turtle dive which purrs like a cat! The other 'pest birds' you mention are also very cool, I'm especially fond of starlings, they have tons of character and I love watching them on their winter roosts. But then again they're not the problem here they are in the USA... Gulls are usually only aggressive if they're defending young or if they learn to associate people with food.
Although not maligned in the same way an unpopular group of birds (at least among the general population) I really like are the laughingthrushes. They are beautiful, smart and highly sociable birds with interesting vocalisations and cooperative breeding behaviour in some.
