I personally find the Alvas to be lower quality than other cheapies, just based on the microsuede/fleece inners. They're just not as nice and soft and they pill very easily. They also haven't held up very well compared to other cheapies I have (sunbaby, go green, kawaii baby, some random nameless ebay ones). The alvas I have also run larger than my Sunbaby size 2s, so the sunbaby size 2s fit my youngest at 2 weeks with no leaks and I haven't done more than try Alvas on him because there are such large gaps at the legs. If you're still looking for some cheap diapers, I really like sunbaby ones. Their inserts (I have both bamboo and blend inserts from sunbaby) are nice, too. But again, you're looking at a potentially long ship time (though in the life of diapering 2-6 weeks is the blink of an eye). Mine have held up for 2 years now and I bought many of them used to begin with. If you wanted to look at alvas without the super long ship time, I find that the prices at https://www.getbacktobasics.net/ are pretty good, and it's cyber monday.
ETA: I also find that I don't like Kawaii inserts. The "bamboo" inserts I ordered were actually two layers of bamboo and two layers of microfiber, which is why they were so much thicker than other bamboo inserts, but they actually don't hold as much pee as you would hope by their thickness. I think I've tried alva inserts (they came with a random set of used natural fiber inserts I bought) and they were okay, but I can't actually be sure those were made by alva.
