Hi James,
I am not sure if others will agree but to me, the use of 'satisfaisant' (which is just 'pleasing') is not the same as gratifiant which is much stronger and closer to 'rewarding' ( which you get a lot of satisfaction/reward from).
In any case, we often use synonyms and add others suggested by users but that isn't always possible.
Having said this, if you feel aggrieved, you can always mark yourself up...
