I prefer the shape, the winding, the hands - although the 5101 mechanism is impressive, visually I find the mechanism far more engaging on the LF.
Also not a fan of the writing on the dial - but this applies to both references, so it’s a bit of a draw for me (the Patek would look far cleaner without both “10 Days” and “Tourbillon”, although it is more coherently done as labels for the two subdials, effectively - while the writing on the LF is pointless). At least the LF writing is in a subtle grey…
