IMO the E46 LED's look quite modern and blink much more brightly and engage more crisply than any E9x lights right now since they are true LED's--both braking and just driving around. And they have adaptive brake lights, an extra ring that engages when ABS is engaged...
I think E46's have different "dated" features such as the strip moulding down the body lengthwise and general boxiness... but the tail lights definitely look great for the '03.5+ LED's.
It seems as if you and your g/f place a lot of emphasis on tail lights. For me personally, I have never given a second though to LED tail lights. The E9x looks better from every angle.
