I didn't think twice about the Mercer when I first saw it revealed, but when I saw it in store, I thought it was pretty cute and I liked all the pockets. I thought it would work well for me. I went back and forth trying on the Mercer and the Rogue 25. I didn't get either but I remember thinking that I might if they went on sale. Actually that day, the SA offered me 40% off the Mercer and I walked away. It felt like too much pressure, so I guess I wasn't in love. I think the Rogue was a little heavier. They didn't have any great colors of Rogue at the time I was in the store. The Rogue might be better for me because I'd rather have a shoulder bag than a cross body, but the Mercer is cheaper.
The other reason I'm seriously thinking about the Rogue in red is because I fell in love with a red bag of another brand that is much more expensive, so if I loved the Rogue just as much, it would be like saving $1800!
I've never liked the regular Swagger for me as satchels aren't my first choice but the Swagger shoulder bag I've always liked. I think I saw a reveal where it was obvious it was way too small for me, so it is something I'll just admire on other people.
