HIMYM has better writing, and I like the creativity of the time jumps, and different versions of the same scenes. I think it makes the storytelling aspect of it more fun. Plus HIMYM can sometimes can go to a very weird place, which I like. On the negative side, they're really dragging the Ted/mother thing out waaaaaaaay too long. Friends is your standard three camera sitcom, and had some very good, fun, memorable moments in it, but I still prefer HIMYM. For a cast, everyone on Friends had some great moments which made for a great ensemble. Neil Patrick Harris just blows away the rest of the HIMYM cast and too frequently is the best part of the show. I'll give the Friends cast the edge on acting.
