wish you were local so you could borrow mine for a couple of days
voiding warranty with tune didn't concern me- AMG ran the motors at red line for 5 months continuously then gave up trying to get it to fail
interior,stereo, performance, ride quality, exhaust (stock in sport+mode) are all better then my Gen1 R8
looks is all subjective but R8 is sexier and more exotic looking
GTS makes a better daily for me
GTS also kept me from having to do lots of the mods I did in my R8 i.e.: GTS didn't need exhaust, upgraded steering wheel, red seat belts, rear spoiler, forced induction...
so funny how AMG forum criticizes R8 and opposite is true here- I have no bias or brand loyalty and can say both cars are awesome
