"which of the following can give the best home theater experience"
My experience with most of this stuff is that it's not going to be that critical, regardless of which - otherwise quality - woofers you use. What you mentioned are all going to do well IF - THAT'S A BIG CRITICAL "IF" - you set em up properly, as well as the rest of the room, seats, speakers, acoustics, calibration, tweaking, etc!
I have sold the most expensive subs on the plannet in many hi-fi stores over the years, done custom jobs, and owned one or two my self over the decades. I've had everything from Entec's, Big Dunlavy's, Martin Logan's best, Wilson's $10k woofer in my store, the Velo's (of course), Earthquake's, MK MX5000's, Paradigm Servo 15's, Thiels ultra pricy boogers, and more! This I can tell you, and that's that a single woofer, by itself, is not going to make or brake a system, or simply blow away another (or multiple) properly setup and dialed in, otherwise capable, subwoofer from another company!...epecially when you're talking about a home theater system.
Actually, for the money, I've found that the Paradigm Servo 15's offer the best blend of accurate musical qualities, control, etc, vs. sheer output and dynamic range! (especially when you consider the size of the spaces these speakers usually end up in. (most domestic rooms are relatively small acoustic spaces).
All that said, I've never been a fan of the Velodyne's for movies/music, even the Servo models.
Right now, the JL's are getting all kinds of coverage and press. But you must consider all that as largely marketing, advertising, and "reviewer incentives", when considering. Basically, everyone in business has an agenda. You can only try for yourself on the used market.
Then, there's almost zero downside, as you can sell if you dont' get good results, and try something else!
Off hand, I'd probably go with the JL's if they fit your price range over the Velodynes. However, depends on the deal. If I found a great stellar deal on some woofer somewhere, I'd be inclined to go that dirrection, knowing what I know, that is.
