This was recommended by dentist for my dad, not had any issues so far, ymmv

If you read the ingredients on the different brands like fixadent and polygrips, there almost identical. I think you'll find most of them are very similar bar the odd thing here or there. Much like most things. Might even be worth looking at an own brand one.
