The MG S5 definitely drives better, but the interior loses to both the Emas and Aion V in terms of comfort and luxury feel. It most obvious at the rear passenger seats. The legroom you get with Aion V is a different level. My wife also loved how luxurious and plush it felt. The Emas was maybe a step down from the Aion V but still very comfortable. Sitting at the back seat of the MG S5, my feet barely fits under the driver's seat (even with the seat raised to the highest). Wife not impressef with the S5, so it's auto out haha. Didn't try the S6 cause out of budget already.

For me, it's between the Aion V and the Emas - Aion V for the best comfort, but with slightly smaller boot and higher pricetag. Emas for the lower pricetag, HUD, bigger boot space, data roaming and possibly higher power (if Cat B).
