I have experience with the Tena flex, but not the depend adjustable. I like the tena flex maxi. really good absortion. the only issue I have is that because the front of the diaper attatches to the "belt" I can't seem to get a tight fit that I would like. It would be nice if the belt attatched to the diaper, kind of the the belted diapers. althought the point of the belt is to keep the diaper on while using say a urinal if one had the opertunity. but anyway, I do recommend them. but not for night time use.
