i had a 2.4 Accord prior to my Lexus, albeit a 7th Gen. The Lexus far better, i almost did buy a 8th gen 2.4 but the spec and gadgets on the Lexus trumped anything on the range topping ex trim on the accord, I have no doubt the Lexus is much better also.
My standards since buying this car have gone up a notch or 2 as I am looking out for a cl55 now.
btw, I get better mpg on my is250 than my old accord.
