Aren't Jehovah witnesses just like any other Christian religion?

One came up to me while was waiting on the bus. it was funny how they caught me i saw a group of walking and talking to people so i ran the other way into the building. when i sat down i saw a good looking well dressed girl walking towards me i thought she wanted talk me about something but she turned out to be one of them i would've turned her away but i thought maybe i could get a date instead of a sermon.anyway that was a big fail and she kept going on and on about how that when God comes back only so many are gonna be brought back to live on the new utopia earth i some stuff like that but everything she was saying is what every other Christian says.So i asked her so is isn't being a Jehovah witness is just like being the Christian i already am she said no and that she really couldn't explain but she come to my house and discuss it with me some time so i said yeah that would be fine so she told me she'll see me saturday at 9. so i got already that saturday morning and at 9 i saw a car pull and just knew it was her but instead of her 2 old ladies and a man showed up so i didn't answer the door. anyway i still didn't get answer for my question Whats the difference from being Jehovah and a regular Christian?
