1. Bambino Magnificos, if it weren't for the price I'd use them all the time. The comfort, fit, look, it's all perfect, and the stretch wings and hook-loop fasteners are almost impossible to break.
2. Abena L4s, these are my primary diaper. They aren't quite as unbreakable as the Bambino, but they're the old reliable of adult diapers for a reason, and while other diapers have probably surpassed them in absorbency, these hit a perfect spot for how much I can use a diaper before an inevitable BM or skin irritation sets in. And they're the best price-to-performance diaper on the market.
3. ABU Space, the only thing that prevents me from getting them more often is again, price. But they're so comfortable, and so cute that they're worth it if you can afford it. I'm not a big fan of the landing zone system, the hard plastic is what sets them just under the Magnifico and the L4 for me, and before I lost weight I had a problem even getting the tapes to reach it, even well within the stated size range, because ABU does have a habit of not upscaling the landing zone with the different size diapers. I have a dream that one day ABU will employ a similar taping method to the Magnficos and just blow everyone out of the water, as it would solve the only problem I have with them.
3. ABU Preschools. I need to add these more to my lineup, the backing is the closest to baby diapers on the market which hits me right in my little feels, the price point is just amazing, and for a diaper that only advertises as a day diaper specifically, it has an impressive absorbency for that category. The same landing zone issues apply as the Space, but they're slightly less annoying just due to the backing having a bit more stretch to it.
(I do feel the Preschools and Space deserve their tie positions even if they're for different niches. If ABU ever did decide to release my dream diaper, it would have the Space absorbency, the Preschool backing, the L4 Pricing, and the Magnifico taping system. That would be the best diaper, easy, and I would never buy anything else.)
4. Tranquility ATNs. When I'm low on cash, these are the diapers I shoot for. Best price for an actually functional diaper on the market. They're not quite as absorbent as the above, probably on par with the Preschools if I were to hazard a guess, but they're functional, and at $1.22/diaper it's a price point few others can match at that level of absorbency.
5. Confidry 24/7, admittedly I tend to only get them if there's a supply problem on one of the above. They're certainly one of the most absorbent diapers, to the point that I only rarely make full use of their absorbency due to diminishing returns because of the fact that I have to get changed eventually regardless after so many hours due to the aforementioned BMs and skin irritation, but they have some serious drawbacks for me personally, mainly the backing. It is actually TOO sturdy for me. It tends to actually cut into my legs after prolonged use and becomes really uncomfortable. But they'll do for me in a pinch, and I have basically zero fear of leaks when wearing them, so they do make my top 5 nonetheless.
Honorable Mention: Seni Quatros, a couple of years ago they probably would have placed as high as #3 on this list, but then they went through a redesign not too long ago that massively downgraded their quality. The old design with the two pink stripes was an incredibly efficient diaper with one of the best backings on the market, not too dissimilar to the Preschools but with Absorbency more in line with Abena. They were previously in my regular rotation, but the absorbency and build quality just died in the new ones with the single peach stripe, so they've basically died to me as a product, but I'll lament their passing nonetheless, and the old design deserves a mention here.
