but one says 238G, another says 1000G, why is that

Prorated means adjusted calculation because the Linode was not alive at 1st of month. When you set up a new Linode, in the first month you pay for - and get a quota for - the days remaining in that month, and not the whole month. On 2nd month, the "prorated" note will disappear and you will see the quotas exactly equal.
