I wanted a good pepper mill and recently bought the Peugeot U-Select 9"

I like it a lot. I've never use the Atlas so I can't make any comparisons. The U-select feature is used to adjust the grind. The bottom few inches of the mill can be twisted relative to the rest of the body which allows a quick alteration of the grind and it has reference marks for personal preference. The mill comes with a tiny little guide attached that mentions the peppercorns should be 5mm or smaller.
Just to be sure that size wasn't going to be an issue at the same time I bought the..

..a 1 lb package of Tllicherry whole peppercorns, on arrival I emptied the mill and filled it with the Tellicherry. No problems and the first words out of the wife's mouth were "restaurant pepper". Our last lexon mill had broken and we were limited to the canned pepper for quite a while. The 1lb of peppercorns is $13 and just about filled up a quart jar. I don't think we'll need pepper anytime soon (but If someone has a favorite pepper I'd love to hear about it).
I'm not pumping Amazon which frequently doesn't have the best price, it's that I took out a one month free trial to Amazon Prime for the benefit of free 2nd day shipping. OK, not that I believe anything is really free, they're hoping you keep the membership at an annual cost of about $80, I didn't! None the less, the "free shipping" motivated me to make some extra purchases, including the Pepper Mill.
I almost forgot the most important part, to actually address your question. I normally grind towards the fine side but I used the U-Select and switched the mill over to the most coarse setting, I don't know how this compares with your mill but here is the result.
