He had a .349 OBP last season, he has a .340 OBP this season, and he's going to hit 30 HR again too while holding down 3B and now 2B. He was the best player on the team last year and he would have been again this year if we didn't have two MVP-caliber additions at the top of the order. Yelich and Cain are more valuable obviously, but Shaw repeating his 2017 breakout is one of the most important reasons we are where we are. If Shaw had regressed like Santana and Arcia we might have Sogard starting at 3B right now. (Only half joking.) That's why I give him the nod over Aguilar, since even if Aguilar had stumbled we had other adequate replacements at 1B.
