here's some reviews about both of the diapers but the most absorbent is the Dry 24/7 while the NorthShoreSupreme takes all the positive ratings with putting on, taking off, good absorbency, etc. The Tena Slip Maxi is a good starter plastic diaper as well which has a review on ADISC right here:

The Dry 24/7 might be the most expensive but stretches and fits right on contact, very absorbent (From what I've heard, it can take up to 5 or 6 large wettings), it is a plain white diaper of course but it's one of the top 5 out there so you already were hugged by heaven so I say. It's good with it's odor control and can last you 7-9 hours because with it's high in SAP, you will hardly leave a dent in these before you can even try! These are the #1 in best diaper, #1 in absorbency, and #2 in pricing.
The Tena Slip Maxi is a good medical and sizing diaper, although not as bulk as everyone wants but can withstand some pretty heavy wettings. It's a nice diaper overall that has been out in a long time and still stands as a good starter diaper to try. It's somewhat good at odor controlled and can last you 5-7 hours. The pricing is a tad bit ridiculuous but one can't argue over it's performance. pack of 24 for $35. #3 for best diaper, #3 in absorbency, #3 in pricing.
The NorthShore Supreme is a somewhat new diaper but already marked it's grave as a top-tier tabbed diaper. It absorbed alot of wetting and is really easy to put on and put off. It is completely odor controlled for any smelly urine you throw at it and will last you for a good 6 to 8 hours. I'd say these are worth a shot of you want to save money and want something simple other than Tena Slip. Pack of 15 for $21. #2 for best diaper, #2 in absorbency, and #2 in pricing.
Out of the three, The dry 24/7's are good but if your trying something new, then try the northshore supreme!
