Best Trio and Best Out of the 3

So, I've seen the full UK version and I'm about halfway through the US version. I was wondering which of the three trios (Mitchell/Annie/George, Hal/Alex/Tom, or Aidan/Sally/Josh) everyone else prefers. I think my personal favorite trio is the original UK, followed by the second UK trio, but I DO like the US trio.

Also, I wondered who is everyone's favorite vampire, ghost, and werewolf.

My favorite vampire is definitely Hal, but I adore Mitchell too. I like Aidan, but I'm finding him difficult to fully love.

My favorite ghost is Annie. She's powerful, but also adorable and the glue that hold everyone together.

And, my favorite werewolf is Tom. George was wonderful, but sometimes a dick. Like how he cheated on Nina and never told fessed up to that at all. Josh is GREAT, but he pales in comparison to perfect baby lamb Tom.
