The Delta Club Room is a nice lounge but it's quieter, with usually plush seatings, deluxe bathrooms, an open bar, some snacks - Fruit, cookies, magazines, newpapers, and television usually running CNN. I think internet access (I don't need to use it in the airport usually) and in LA they have a putting green.
Since we're using FF miles into FLL, we're flying 1st class, but, we also use AMEX Platnium. That card has some really nice perks - We get $300. on board credit as well on Regent among many other things like prefered seating at concerts and theater. We try to fly Delta so that we have the benefit of using the lounge when we do fly. I can already feel that massage - it's how I am spending my onboard credit!!
