In this instance, the "S" model (at least for 2013) came with standard headlights and the SV & SL trim came with LED headlights IIRC. The light output is dangerously low on the "S."
LED low beams were an option on the SV, not standard. Mine has what I guess are the same halogen lights as the S, and the low beams are perfectly fine. It's the high beams that are terrible, and you get that same halogen high beam setup with the LED option, IIRC. If you have terrible low beams, then you have a problem with the lights in your car, not a design defect.
