I had a pair of Patagonia boots with aluminum bars - they were downright dangerous on dry rock! Fine in the water (a little heavy), but climbing around the banks was ridiculous!
I had a MUCH better experience with mine.
I recently put mine to the test in Alaska, wading the area around Kenai and Russian River confluence in unseasonably HIGH flows. All I can say about their grip on the slick rocky riverbottom is I have NEVER felt more fearless and invincible in strong current than I did wearing these boots. 100% ROCK SOLID TRACTION!
Fit is fantastic. Foot entry and exit... EFFORTLESS, best I've EVER had.
The downsides?
1) Laces. I've gotten used to the BOA system snowboarders use. But that's really just personal preference.
2) Poor drainage.... and unless inverted with open air circulation on a sunny day or mounted on a PEET Boot Dryer... they take a LONG time to dry.

Think about it.... NOTHING stickier on rocks than a bare aluminum driftboat bottom
Here's what they looked like after a 2-day break in period...

I wore them the rest of my Alaska season... wading the Nush swingin' the double hander with George Cook, then back to the lower Kenai for kings, sockeye, coho, and pinks. Not nearly as challenging for wading, but every step inriver was taken with supreme confidence.
I had some concerns about traction as well as wear/tear on the new diamond plate floor we put in our Kenai Predator, but apart from the extra noise of metal on metal, it was a non-issue.
