The Office(US) vs. The Office(UK)

So now I have watched every episode of the American and British versions of The Office. I loved both show, and for how much the are similar, they are very different. It is funny how you can have two shows that started with the same episode, have similar plots all the way through, and yet be two completely different shows.
One big difference in the shows is the level of humor. The American version has an in-your-face "Seinfeld with a touch of slapstick" humor. I literally laughed out loud at least once during every episode. There are really no favorite episodes, just favorite moments. Meredith trapped in a bag with a bat. Hilarious. Arguing about Alfredo's pizza. Hilarious.
The British version has a British comedy style where there are a couple of laugh out loud moments here or there, but even when there are none you sit back at the end of each episode and think, "That was hilarious."
The second big thing is the characters. Of course the American version has had way more episodes then the British one, but the characters are way more developed, and more cared about. In the British you have your main characters,(David, Gareth, Tim, and Dawn) but that is about it. They don't explore the other workers as nearly as they did in the first 12 episode of the American one. My favorite character is Toby. Toby is a background character who shows up every once in a while, but I feel like I know Toby, he has been explored. In the British version I'd have to say my favorite character is David, but David is the main character, and also played by one of the funniest men on the planet.
The plots are both very similar. Beside working in an office, one office has to incorporate another one, the main male character and the engaged receptionist have a thing, the main male plays pranks on his desk mate, the desk mate is a spazz who thinks he is more qualified then he actually is, and the boss is a humor loving moron who wants to be everyone's friend.
All and all I think no one series is better then the other. They both have there high points, but neither stands out ahead of the other. I don't know if a cross-over episode would be cheesy or brilliantly funny.
