Great thread, and call me subjective, but I think color-matched its in a class of its own. The bumpers don’t need to be perfectly identical—mine are slightly bolder, and I like that. It makes them stand out as an accessory and avoids looking like a bald person without eyebrows (no offense).
By the same token, there is nothing wrong with black powder coated bumpers especially as others have mentioned, on an Iconic Silver and if you have BAP. It's almost a no brainer but, color matched would look equally as great. You have two great options and I am also a perfectionist (which drives me nuts at times) but you will not go wrong with either.
I can’t speak to the resistance of powder coating in your harsh, salty winters, but mine were powder-coated, and with the use our truck gets, they’ve held up just fine for nearly three years.
As
@Vecman mentioned, the corner cutouts for a normal shoe size are fairly snug but they work. With tennis shoes, you should be able to wedge your foot in just fine, but for that, I’d use the rear bumper, which allows more space and you can just hang on easier since your foot goes in further if you get what I mean?. I rarely need just the corner to look into the bed or if I am going to hop in. I feel it's easier to simply use the bed step which we use day in and day out. I think those corner cutouts are more geared for 14-year old; I know the 14-year will simply put his foot in there and hop up in the bed with no problem but he is also 125lbs. (them were the days

)
Look at the inches side; not the tenths side (engineering units)
The cut out is 4-1/14" wide by 3" tall

One downside is that
unless CU now offers rear bumpers with license plate lights, there aren’t any cutouts for them—a big con, in my opinion. I ended up adding them myself (not easy with such thick steel) and used Morimoto license plate lights. They provide bolts with integrated lighting, which is neat, but why neglect standard plate lamps? (I never did get the lighted bolts to begin with but I am sure I was only 1 of a million).
I didn’t fully follow the comment about the tailgate, but ours is used throughout the day, and the bumper has never been an issue. There is a small gap compared to stock due to the black insert piece from the stock bumper at the bottom of the tailgate but it's never been a big deal to me. I also have the dually light, and it doesn’t restrict visibility.

The bumpers are modular, meaing they're 3 pieces but that hasn't been an issue so far.
The light cutouts are 3", perfect for recessed Baja Design Squadron Pros.

My rear auxiliary lights are all wired separately.
The only ones tapped into the factory reverse lights are the license plate lights as shown below (now 2 light bars).

Lastly, I have dropped the spare a few times and the opening as not been an issue other than removing the plastic "lock" which again, due to the thick steel (and the collected grime) can make it increasignly difficult to turn.
