OK, after more thinking, I believe I was incorrect about the pink chips. You are correct, they are much sharper edged than the original cards mold chips. They are actually from Sean's Batch #4, not Batch #5. I hadn't noticed how nice and sharp they were til you pointed it out!The right stack is so much nicer for sure. It just depends if you prefer squared off edges or rounded ones. It's an easy pick from those 2 stacks next to one another for me. Easily the pink ones.
And for some reason those purples look way worse than others that I've seen. I'm going to gather up chips from several different batches and do some comparative photos. It may be a day or so though before I can get to it, as I am swamped with both work and other personal projects right now.
