Beyonce is an amazing performer. I saw her live and she simply oozes talent. Sadly, that's where it all ends because her ability to control a crowd is VERY lacking. She only "talked" to the audience ONCE throughout the whole show and she never even mentioned the name of my city/country. It felt like just another show instead of an experience or a connection between her and her fans. The only thing I could say after the concert ended was that she was an AMAZING dancer and singer... but that's where it all ends.
Meanwhile, everyone couldn't stop dancing and jumping on Gaga's tour. She made the concert feel so personal, talking about the typical foods from my country she had eaten since she arrived, saying random jokes, bringing like 30 people on stage, or just screaming for people to jump and dance. It was really an experience. Even on Rihanna's tour I felt much more "closer" to her than on Beyonce's tour, because she also addressed the audience various times.
This is just my opinion, of course. But I'm honestly being as objective as possible. Her concert felt like just one big performance and not like an actual dynamic experience between her and the audience. I wouldn't pay to see her again.
EDIT: I thought this meant tours and not just performances
It's safe to say Beyonce is the better performer on televised shows.
