My vote goes to home. I love a good rave don't get me wrong, but I find that I consistently roll harder when I have a critical music listening session at home. It really comes down to the music for me. (also the audio gear you use)
At home, especially with good headphones (you need to spend decent money on headphones, possibly amplifier and dac for it), you are completely isolated from any other outside noise. It's just you and the music. The sound quality is amazing. You hear every single detail and instrument separation that was originally mastered into the track. This will take your mind many many galaxies far away. It can be very breathtaking.
At raves, there's just too much going on which makes it hard to fully focus on the music. Not to mention all the other ambient noise going on at a rave and so many other things. Hence for me, when I roll at raves its less intense of a roll because my mind is paying attention to so many other things and I can't let myself become completely immersed in the music.
Lots of other reasons too why I prefer home.
