I haven't used the Atlas, though it looks like a sound basic trekking / walking jacket - one day someone will explain to me what the difference is, other than the odd penchant of the manufacturers to produce all 'travel' and trekking clothing in shades of beige.
The one thing I would be aware of is that the Atlas uses 'Triplepoint' rather than the top-end Triplepoint Ceramic. My experience of the former is that it's not quite as breathable as the more expensive version and can get sweaty under duress, but to be fair, work hard and evern the most breathable, breathables on the market won't keep up.
If it fits you decently and you're happy that there are enough pockets / the hood's a good fit / you like the style etc, it looks like a good buy at the price.
