To be honest... I don't think there will be much difference between Dakota leather and Sensatec in that regard. The Dakota leather is so heavily processed I find it very hard to believe that it still 'breathes' like people tend to claim.
In my opinion: If you don't want a sweaty back you should just get cloth.
Leather looks cool, smells nice and is easy to clean, but it's also too hot in summer and too cold in winter. And you'll slide around in the seat more when cornering.
