I originally started out with kissaluvs and bummis and bg3.0s when kiddo was born and as she grew into the bgs. once she grew out of the KL's (size 0) I started wondering if I'd like something else and just bought cute things off hyenacart. After awhile I ended up deciding that I liked fitteds and covers best and didn't reach for the pockets often. Eventually I tried prefolds and really started to dig those. Finally got up the courage to try fleece and then wool.. yup, liked 'em more than PUL. Finally decided I wanted to go really old school and try flats.
Â
Now, I prefer to use only flats and wool during the day and a really good fitted and wool at night (I love BSRB best but find them hard to get.. thankfully I have enough now for nighttime dipes)

I think you should definitely try a few things rather than investing in only one or two you might not like. Definitely try a few different STYLES. I wish I had started with trying styles rather than assuming I'd only want pockets. There are pros and cons to all styles and you might be surprised. I never ever expected to want to do prefolds or flats. pins and snappis and folding and so complicated! but wouldn't you know it, I only like pockets/aios for husband/babysitters or when I NEED something really fast.
Â
I was able to decide what I liked after a few uses... but my needs kept changing so where I didn't like something 2 months ago, I ended up using it a lot later. My perfect stash definitely has a variety of things. Heavy on the flats/wool and fitteds but still some pockets/aios and some thirsties covers as well. There are some brands I don't like at all because they don't fit my child well (or in the case of bella's bottoms, were too thin and wore out too fast) but mostly I've found that style is really what matters. All fitteds are pretty similar, all pockets are pretty similar. The cut can be a bit different and the material can be different (all cotton isn't going to be as absorbent probably as cotton with some hemp layers for instance) but mostly the differences are small.
Â
So to sum up... try a few styles.. get a couple types of pockets, get a couple aios, try prefolds and a couple types of covers. a couple types of fitteds. Choose whichever brand you think might be good, either through recommendations from friends or because they just seem really popular (BG's sell really well haha) and as you use that first stash you create, you'll learn what you reach for right away, what you can't stand to use, what is harder to wash, what doesn't fit your child or irritates their skin and you can buy and sell to adjust your stash accordingly. After two months, you'll already have a pretty good idea of what you like even if you have only one of a particular style/brand especially if you buy only about 24 diapers and you can definitely sell diapers only used that long for most of what you bought them for which will fund whatever you want to buy to replace them. you can also buy used to save more money while you figure out stash nirvana. You can still sell used too to fund more fluff :D
