If I wanted to continue an existence similar to "real life", then it would probably be the Kuriotates, and just hope that Cardith tries to keep me and the population happy with Fellowship trees rather than a tower of complancy and a lot of undead water-walkers. Cassiel and the Grigori as well for the reasons stated here. In a world where pretty much all the religions are rather fanatical, steering clear of it entirely would probably be the most "pleasant" way to live life.
But personally, I'd want to live under the Balserapths (call me crazy

).
Streets paved with people dressed in all manner of unusual clothing. Carnivals at every turn (I assume that comes with Cotton Candy too, yum!). Once you get over the moral conflicts of finding enslavement sickening, you can enjoy both animal and human shows. You have Loki running around Entertaining and Inspiring you... when he isn't busy annoying the neighbours and bringing in a fresh batch of immigrants to Jubilee.
Even going to war is a dance-like show. Strange mutated creatures on one side, cheerfully painted Merrymen on the other side. At the front (or back, or side or above, you never know) you've got homicidal Harlequins dazzling the foe with all sorts of unconventional offence.... or the good old fashioned thwack them on the head really hard with a stick method. It depends what kind of Harlequin they are. At the very least you know they're going to make your first attacks a little quicker.
Your mages make a show of it too. The usual way of summoning beasts and spells isn't good enough for them. First, they'll bring a puppet into existence and then command their puppet to do the spell for them. And you have the very elite core of your army. Your very best champions, who after drilling a sword through their foe will happily take note of their foe's best abilities and put them into practice against the next opponent.
Even if you're marching to your death, it's got to be a more cheerful affair than marching to your death in a conventional manner. The only frustrating aspect is you're probably marching to your death because King Peppy saw a really nice hat in your neighbour's city and demands the army capture the city so that he can obtain it.
As for day-to-day life, Eldric IV said it in the most fun way:
As soon as you think you figure something out, the Belseraph reality would come crushing it. It is not "everything you know is wrong; black is white, up is down, short is long." That is contrariness and easy to grasp. Rather, it is "everything you know is flapjack; purple gravity, bird is employment, cthulhu fhtagn." (And yes, I found OO every time I play Belseraph.)
Real life is boring. It's why we play video-games

Screw working hard for my position, getting by on my own talent and all those other things we're used to. Make Peppy (or Keelyn) smile and you'll probably get that upside down mansion Tyrs promised. Paint cows green to see if it increases their milk productivity and you'll probably upstage all the best advisors in the land.
Even if you end up in the slave cages, Beeri proved that if you're amusing enough you'll be let loose, and whilst he may speak in tongues, Perpentach won't go back on his word... it's just a matter of trying to translate what he said into normal-people words.
As for Keelyn, she doesn't seem too hard to amuse. If you're a Bard, play a really pretty song (on a Lyre perharps) and you'll be in her good books. If not... try to stay on the good side of her "friends".
And as Kael said:
sanity is overrated.
Also, I rambled on way more than I expected to when I entered this thread. Lore threads are fun, stimulate the imagination
