both. they PME and Langevin serve different purposes.

please understand, that this is not the right forum to discuss such
fundamental matters. get hold of a text book on molecular dynamics
and look it up. ...and then find somebody locally to discuss topics
related to MD. these kind of questions are so much better answered,
if you would spend some effort in figuring them out by yourself and
then discuss your findings with somebody more knowledgable in
