I've got a set I have been running on a 640 Pro...
I'm not sure how they compare to the Hogue grip since I've never had experience with the Hogues. However, I like these Altamonts.
They are comfortable and fit my hand well. Fit and finish are excellent. Recoil absorption is not what you will get with rubber grips, however even with 357 Magnums I don't really see a problem.
The one issue I've seen is interference with a speed loader. With the pictured 640 I have a moonclip option And they work without interference. If you carry your spares on a speed strip like I do, there isn't an issue.
Overall, I give them a thumbs up.
