Northshores are great in either air supreme or (plastic) supreme. Cant remember the last time i had a leak with them. If thickness and absorbancy is your main then the baddest white diapers are the inspire + and the bambino biancos ultra stretch. The bambinos are my favorite and I've only tried a sample. Thicker and wider than anything yet fit perfectly due to their stretch system. They feel like regular pull on underwear and the tabs stay put. The tabs are a heavy duty hook system that mimics Velcro. They come off if you want them off, and go on like it's the first time you've put them on. The rearz are super thick and will soak up a lake, they're traditional plastic white diapers with 4 wide tabs and a landing zone for refastening. With both of these diaper under normal fluid intake, your skins health and ability to walk will be an issue before leaks. Abenas are good for every day but are seeming a little more outdated evertime put one on. ABDL diaper manufacturers are catering to us and know what we want. Bulk, crinkle, absorbancy. I know you mentioned you don't like AB diapers but super dry kids by ABU are fantastic as long as you can tolerate the design. They're a joy to wear and change in and out of with just 2 big tapes that don't budge. I would say they hold about as much as a premium abena and have huge leak guards that allow for big boosters and confident messing.
We're in the hay day of AB/DL diapers. I emailed northshore about putting some underwear-like prints on their premiums and they said it was already in the works. No promises though. That's why my favorite is always the next one that comes out.
