2016 Felt AR1 or Felt AR2

My LBS has the 2016 Felt AR1 and AR2 listed at the same price. I’d really like to get back into the Di2 world, however the AR1 has nicer wheels, crank, stem with DA mechanical. The AR2 comes with ultegra 6850.

so question is…if the they are the same price and thats essentially the budget, which one do you go with?

thanks in advance…
