Interior quality and material much better than Sushi, design is subjective. Refinement slightly inferior, not much different to me.
Quality control for T is good, K not as good but at least much better than H.

Service working attitude not as good but most SC are the same, it depends who and which SC you deal with.

Currently driving Sushi after I decided not to go continental. Have you bought yours? My ex-Kimchi served me well for the past 7 years.
If you let me choose between Korean or Japanese for next car, most likely I will get a Korean car if the design in and out fits my taste.

Totally different segment, it will be hard to decide. Currently Civic looks really sexy and nice compared to other cars available.
It depends on age I guess, if you look 40 years old come out from Civic feel like ahbeng. If you drive 5 years, 45 years old ahbeng.

Dont think Japanese FC is as good as most assumed, mine is drinking macam FOC at city drive.

Hyundai is not doing so well in MY, there are still Elantra and Sonata year 2015 for sale. Last I checked Sonata selling at RM99K.
