Acura and Infiniti were arguably never up to even Lexus, let alone the almighty Germans. Lexus certainly had their moments-- many have been brought up above. Now, the begin and end all of Lexus are predator grill RX350s sold to people on their way to the nursing home. Simply put: they're the Buick/Cadillac/Lincoln of today (I forgot those three still exist). Cars like that certainly have their place, but when it comes to prestige and posters ending up on a dreamy-eyed teen boy's bedroom wall, forget about it. Absolutely no one dreams about an RX or GS/ES/LS. Their LC *could* change that; I could see it being the dream car of a spikey-haired Asian kid who lives off of energy drinks and drives a WRX.
Me, personally, the only cars I liked that Lexus produced were their SCs from the 90's and 2000's, as well as all of the LX and GX except for the predator iterations. That. Is. it. Most any other car that Japan produced that I liked were from the 1980's, and they weren't from their luxury badges which were created out of thin air. They were the Datsun/Nissan Z cars, the Toyota Celicas from the late 70s, almost every two door Mazda and Subaru SVX. Japan hasn't made cars like that in many many years; Their luxo brands, forget about it.
