Haven't used many others since finding what I like but here's what I've been using for a while.
Abena Boost(
aka Abri-let Maxi) are decent boosters.
Coverage is great(24in long, 6in wide) and absorbency is alright. Start out thin but swell a moderate amount.
Rears Boosters are my current favorite and are very good quality.
Plush and thick out of the pack, coverage is very good(19in long, 6in wide) and absorbency is great. As stated they start out plush while dry but then swell a lot when wet.
Other boosters I've tried but haven't used in while include:
- Northshore boosters, they're alright but you've already used these. Liked the Large size.
- Bambino Quadro(pre update) were kinda wacky, thin but swelled a ton. Since the update they upped the absorbency so I can only imagine the swell factor now. Sometimes bursted though.
- TotalDry Ultimate Boost Ups were pretty good. Not the most coverage but really did well when I gave them a go. Short but the hourglass shape meant to fit better right between the legs. Somewhat plush and soft and swelled a good amount, but also sometimes bursted.
- ABU Power-ups were decent, didn't wow me but are of a decent build quality. Started out thin but swelled a good amount, didn't have any burst from what I used.
- Tranquility Boosters weren't great. Low absorbency and felt damp most of the time if wet. Didn't swell very much.
