Buy a pack of Tena pants (expensive) and a pack of supermarket own brand (cheaper) and see if you can tell the difference.
What suits some doesn't suit everyone and it is pointless spending a lot of money if the cheaper ones suit you.
There are many to chose from. Most brands have different absorbencies. Do you want pant or pads. Your best bet is to buy a couple of different brands and see what suits your needs best. You might prefer pants or pads with regular pants. Pads might absorb more liquid than pants.
There is a big movement away from disposable incontinence and period pads to cloth and bamboo fibre which can be washed and reused. Not everyone's cup of tea but good for those who don't mind the idea. The pants and pads are a bit pricey but it doesn't take long to recoup the price of disposable
My mum had Alzheimer's and when she was mobile I bought them from Boots and they may have been called Depend or were Boots own brand. These were pull up pants for women and came in various sizes. When she was eventually confined to bed, with carers doing her personal care, her GP prescribed incontinence pants which were open and closed with sticky strips. They were delivered in huge boxes for so many months at a time and were free.
