I have tried lots of diapers and haven't found any that are as soft as the Pampers Swaddlers - so you may be out of luck on that one. I also haven't seen any others with the wetness strip. Since you mentioned that you want them to be unscented, definitely avoid Luvs (they have the strongest scent of any I have tried).
I'll second the other poster who recommended the Kirkland brand from Costco - they work great for us and very rarely leak. We have also used the generic brand from Sams Club and liked those too (might be a bit softer as well). I found the Target Up & Up diapers to be just OK - pretty good on containing leaks but pretty bulky when they get wet and the stiffest of the bunch. I do like Luvs, aside from the scent I mentioned above.
