If comfort is your priority then it’s the Takumi spec (at least here in the U.K.). Takumi has 4-way electric lumbar on both front seats. F Sport only has 2-way. Takumi has very long extendable thigh extender on the drivers seat which is part of the seat memory. No such thigh extender on the F Sport. These were priorities for me, together with auto ventilated front seats which is why I went for the Takumi. At the time F Sport models didn’t have auto ventilated seats but I don’t know if the 2020 models now have this.
The ML audio is stunning and you will not be disappointed as is the HUD - all 10.3” wide.
Personally, I love the Sonic Titanium colour. I’ve had 2 Lexus in this colour and it, depending on the light, changes from silver to bronze-gold. Plus, it always looks clean.😀.
