Session variables are stored in memory for a relatively short period of
time, and Client variables are stored for a longer period of time in either
a database (the best choice usually), the system registry, or a cookie.
Session variables are faster and more efficient in that you don't have the
overhead of a database query, but if you want to use clustered web servers,
you won't be able to use all the benefits that clustering provides and still
use Session variables, which is why they aren't considered very scalable.
