Best Tank for XR650R

[KTMjedi]

HI guys,
I am looking to order a long range fuel tank for my XR and either have the choice of the IMS 17.5 liter tank or the Acerbis 24lt Sahara. Which is best and what distance could I expect from the IMS as this seems like the best choice due to the size etc but I am looking for a bit over 200km range?
