I can say stores and brands like FAAK and YOCY (which seem to actually be the same brand) are honest about the material the dildo is made out of, and also fairly priced.
What you probably want is soft silicone, since it tends to be the most durable and comfortable material.
Beyond those brands, the items that come in black and gold/orange variants also tend to be silicone.
As for artificial vaginas, most are TPE or similar, which is a much lower quality material but not gonna cause any issues if you're just sticking your dick inside. Silicone ones exist but seem to all have monster/animal designs and are fairly pricey.
Like many other things on Ali, (clothes etc.) titles will often lie so make sure to check the info boxes in the item listing.
