I am one of the few, if not the only one, who votes for the round KC type. I love my Hunter bull bar and plan to have KC 123 driving lights on it here shortly (whenever the IRS decides I can have my tax refund, lol!).
I am not sure why, but the LED bars have never looked right to me. They look great installed on other vehicles, but I just don't think they would look all that great on mine. Call me old fashioned. I just prefer the round appearance of the KCs and when compared to no aftermarket driving lights at all, just pure OEM, the KCs give off a fair amount of light (at least the model I plan to purchase). And even though I am one who appreciates light, and a lot of it, I just cannot picture installing the LED bars on my Ram - just not the appearance I am going for.
I have attached some pics for you to consider. It is totally up to you which route you go - much like someone else already mentioned, it is about what look you are trying to accomplish just as much as it is about the light output.
One main reason why I went with the Hunter brand and this specific model, is because, unlike other brands, this one doesn't block most of my beautiful chrome grille.
This is what my rig looks like for now with just the Hunter bar installed:
And these are the pics posted by another member that inspired me to go this route:
