Base V6 or I4 Tech?

i'll stick to my principle of not paying over $35k (before tax) for an Acura. so choices are down to a base V6 and I4 Tech. which one would you choose? i do have a relatively long commute, but most of them are hwy traffic, since the highway gas mileage of the two are similar so fuel economy isn't my biggest concern. i've using the map app on my iphone6+ even in my IS350 which has a navi, so having navi isn't important also.
