Yeah, definately the Acura is superior than Lexus. Amongst the cars u showed, the LS and Rl , LS sells much much more in the US, and the new model
Lexus LS 460- 8 spd auto trans. V8 engine. Very Very quiet engine. Parking automatically. Tire pressure checking for all5 tires. $60k to $72k .
Acura Rl - 6 spd auto trans. V6/V8 engine. Nice engine roaring sounds. Amazing ride with awesome featuers.
Lexus is more comfortable probably but Acura is my car
