I took another look at your photo and dug through my shorts drawer. I have 11 pair of wearable shorts from several different manufacturers and none of them have a pad seam that bad. I think the smoothest seams I saw were Forza Pro Voler and Elite PI. The Volers aren't that expensive. The Voler Elite FS has a smaller pad than the Forza Pro. Sometimes one can find a good deal on PI on Amazon. Good shorts cost money, but they are so worth it.
I use Bag Balm for chamois cream. Many chamois creams are so water soluble they go right away. Although I've got my saddle/shorts interface to where I only use Bag Balm in the rain now.
