Problem with other Ghost shows is some of the crew. I used to love Ghost Hunters with the Taps team, they were my favorite until I watched Ghost Adventures. Taps has a little friction between some of the members and they are not as thrilling as the guys from Ghost Adventures.
Zak Bagans and Aaron Goodwin are usually the two that take the show to greater heights, they are funny and make each ghost adventure really exciting. Zak of course is the best since he seems to really get into it quite a bit. And it seems like they try to provoke the ghosts and catch more on video than the other ghost teams. Sorry to leave out Nick Groff, he's a great guy too.
Ghost Hunters seems to wrap up their investigations really quick, Ghost Adventures crew on the other hand stays all the way from dusk till dawn. Which probably allows them to catch a lot more on tape. The show airs every Friday at 9pm, I tend to miss it quite a lot. But luckily my cable provider has on demand and I can watch reruns.
So if you're in the mood for a great ghost show, check out the Travel channel. You won't be let down by the Ghost Adventures team, they are the best on TV.
