2015 Sonic Hatch LTZ Manual or Hatch RS Manual, with similar price($1500 difference)?

Plan to buy a new car for a long time. I got two quotas from dealers last week. One is for 2015 Sonic Hatch LTZ Manual $18314.0, the other is Hatch RS Manual $19882.0. I saw some shared prices by others in autopriceshare are lower than mine. However, I think both are fair prices in my small city with limited choices... I compared the options difference between these two models and read some reviews about 2015 Sonic. However, I believe that the opinions from current Sonic owners are more valuable, Could any friends here give me some suggestions, Hatch LTZ Manual or Hatch RS Manual?
