Always as night, rarely now during the day. Mainly wear ABU Simple, Space or SDKv2s though I do also like Fabines Panda and Teddy (think I am out of them ATM) and MyDiaper Night are fabulous just a touch expensive here for every night use.
I will give any ABDL Diapers a try and haven't come across one that I have disliked even if they aren't all as absorbent as ABU.
I have loved Kolibri Comslip all white plastic backed Diapers but can't really get them anymore.
Right now Walgreens tape on diapers for the day. For night mostly an AIO or ABU space, little pass. Going to test ABU preschool for day because it is in the price range at the case level of a few other diapers.
If I'm around the house, I'll usually wear cloth diapers (+ pins, pull-on pants) day or night. My favorites are the prefolds from Changing Times, Baby Pants, and flats from Sweet Iris. I also enjoy makeshifting with cloth baby diapers.
But I also like dispies, whether they're the actual baby kind (Pampers, Luvs) or the ABDL kind. I'm currently working through a bag of ABU Cushies v2. My favorite ABDL diapers were the cloth-backed Cushies, now discontinued. And, sadly, the new "Preschool" diaper really isn't any kind of replacement for it.
I don't wear as often as I'd like but for long trips, Dry 24/7 or Bambino Bellissimo. If I could afford it, I'd wear a more practical (like Classico or Bianco or Attends or ATN) for work every day. And if I didn't sleep on my belly/side, I'd wear Tykables or Bambino Bellissimo overnight as well.
Abena Abri-Form M3s both day and night...The few times I sleep padded anyway XD
I've only tried like two other brands, Abena's definitely my favourite... I prefer my diapers thin and cloth-backed, so the M3s fit pretty well ^^
I use Bambino diapers exclusively for now due to price and absorbency and sexy design. I love the new trends of authentic packaging like with Tykables but I am loathe to switch to a company that charges $15.00 for shipping.
Tena Stretch mostly for me. I really like the fit and being able to pull them on and off, and they're decently absorbent for wearing out and about. I have some Abena M3's I've been wearing around the house but I don't like them as much. Also have some Depend pull-ups for real discreet use when I think I might need a toiletless bathroom break while out and about.
I don't wear to bed very often so I don't have anything special for that.
During the day I wear a Leak Master cloth contour diaper and plastic pants. Right now however, I'm wearing a Depends because of a flare up of diaper rash. At night I either wear my daytime diaper with an insert or a night weight (8 ply) prefold diaper and plastic pants. Sometimes during the day I wear a daytime diaper pull up, also by Leak Master, I wear plastic pants over all my diapers
