Ergobaby carrier all position 360 or Omni 360

Hi mummies, im planning to buy ergobaby carrier for my upcoming baby. However theres 2 types, Ergobaby All Position 360 Cool Air Mesh and Ergobaby Omni 360 Cool Air Mesh . Aside from the price, What is the difference and which is better? Or which one did you guys buy and so far is baby comfortable in it ? #firstbaby #FTM
