I have both the lorac and chocolate bar palette, they are both amazing palettes and I love them both. I believe this has more options since you have the top matte and bottom shimmer shades. I would choose this one!
I have both and they are both amazing but I reach for the pro palette more often. It's much easier to travel with and you literally have all the colors you need. I like how there's a matte for every shimmer so you can make thousands of looks without needing to reach for other products. The chocolate bar is great but it's harder to travel with as it's so clunky (even with the "new and improved slimmer packaging") and there's less options I feel. I'm glad I have both and love both but the Lorac is the way to go.
They are both extremely great palettes but I would recommend the Lorac Pro Palette. I believe there is a little lit bigger shade selection and you can get an array of many looks with this. The shadows are very buttery and pigmented with little to no fall out. I love this palette and I think you should give it a try!
