That's a toss up!
I have an 07 SR5 as well. And due to the fact I had to jump on some tires right away, before rims, I have 16" Goodyear Duratracs. No big deal. I like 16" and think it looks great when done right. But, I'm in the exact same position as you, but my vehicle is white. I also have a spoiler and stock bumper... so, for me... I've decided on the TRD rims. I think they are super clean looking and have a really strong presence. I really like those Konigs, and was considering them in another color for my ride, but all said and done, I just felt like there wasn't a lot of "meat" to them. I think they would look better in 17" or 18" for most vehicles.
However, based on your vehicle color, lack of spoiler and the photoshopped examples, i actually voted on the bronze Konigs for you. They look awesome on your ride! Bronze just looks great against the black and it's quite unique.
Of course, the TRD rims are a safe bet, and I'm sure they would look better in person versus the photoshopped picture.
Happy shopping!
