This is just my experience.

I'm still in single digits with astral projection and just reached the teens with LD's.

The only similarity for me so far has been sleep paralysis. I get lucids from from DILD's but have had great WILDs. I usually drift/fall from SP to WILDs. AP, i get the vibrations, and then work myself out of my body/separate.

In AP's i float/swim through the air and doors automatically open for me.
In LD's, i'm on foot and when i fly, it's a big rush
