I'm going to have to close this, I'm not sure if your question has a legitimate purpose behind it but it seems as if you're asking which one has more recreational value.
Diazepam (Valium) and Xanax are both benzodiazepines, while Lyrica is a GABA analogue. It is not a benzo. Don't abuse your medicine if you have a legitimate reason for using. Benzodiazepine withdrawal can get pretty uncomfortable.
