I did a lot of church shopping after leaving the WT and even though I never settled on one I don't regret the experience at all because it helped me to understand why some people do enjoy going to church.
For starters, the children were much better behaved than at any KH I have attended. They either stayed quiet or they went off to Sunday School and did their thing there. Compare that to the KH where the little kids do nothing but scream and cry (who can blame them, really?) and then, in response, their parents do something that has always seem inexplicable to me: they take the poor kid into the restroom and spank him, causing him to cry and scream even louder!
Another thing I noticed was that the sermons generally didn't last over 45 minutes and after that they would actually do other things like choir practice (where they teach you HOW to sing) and volunteer work (Christians actually helping the poor and needy? What's up with that?). There were also games, after school youth programs, and one church even had a singles night for anyone who wanted to enjoy the company of the opposite sex (Oh the horror! The scandal! )
The closest thing I experienced to a KH was a Mormon Chapal. The Sunday service there lasted 2 hours and everyone wore a suit; yet even this was better than the KH. The Mormons still believe in charity. They have activities for singles. And after the main service all the men get together in another room and have discussion about the Bible and theology where you can literally say anything and not be denounced as a heretic (at least that was my experience, though I've heard otherwise from ex-mormons).
Think: the Kingdom Hall is so boring that it makes regular church look exciting by comparison.
