Just received my new model PSM yesterday! I took some comparison photos (below). I still love the look of old model maybe a tiny tiny bit more, but the functionality of the new zipper outweighs the aesthetic!
Here are some points on the pros of the new model I haven't really seen mentioned here (but also, haven't dove too deep)
1. The top stitching on the sides of the new PSM help the bag retain shape. The sides are flatter and stand up straighter. On my old model, they kind of bulge out a bit and make the bag appear slightly more oval.
2. When grabbing something in your bag, the flap opens more evenly since there is no longer that 'lip' where the zipper sits while the bag is open. This also would create a crease diagonally across the front of my bag starting from the zip pull

3. There's a canvas monogram 'lip' lining along the zipper of new model, giving even more structure support to the bag. Therefore it should retain shape better. My old model is softer and a bit more squishy.
4. The new zipper, really is everything. I debated whether or not I should purchase the new model, but I thought I'd try it out. It surprised me! I had no canvas issues with my old model, except I would never close the bag because of the zipper. The new zip is much more convenient, and I can actually get into my bag quicker and zip the bag without having to tug at the corners/ handle like I had to with my old model. Now debating whether I should keep the old model & give it to my daughter in a few years (shes almost 4 now) or if I should sell..
Thanks for reading!
