I'm sure you would love either - really comes down to your finances and expectations. Both bikes are very similar dimensions, and at 6'1" you will find either a bit 'squeezy'. Of course the dearer model is better equipped in terms of wheels, suspension etc. - you do get more if you pay more! I would go for the S model of the larger-engined alternative if you are able to. I was going to wait for the 848 back when I bought the 1098S, but I'm glad I got the better model! More relaxed grunt, similar weight, better equipment - that's the way I would go. Enjoy!
