When this should stay a two-platform decision

trust, safety-related condition notes, and bulky shipping can move the better marketplace more than a generic kids category assumption suggests. Baby gear is a trust-and-bulk category. The better platform is the one that still works after condition confidence, size, and likely accepted price are modeled honestly.
That is why the right answer is usually an order to test, not a universal winner. Different accepted prices, different shipping assumptions, and different buyer expectations can all move the result.
The Smart Order To Test Baby Gear
For baby gear, start with eBay and use Mercari as the cleaner second check. Trust, cleanliness, and shipping footprint matter too much here to let a generic kids category decide the route for you.
Start with something realistic like a baby carrier, activity seat, or stroller accessory bundle in the $25 to $240 range. Run the first marketplace as the baseline, then compare the same sale assumptions on the next-best option before you let platform optimism change the price.
How Audience Fit Changes the Answer
buyers who care about condition clarity, cleanliness, and whether the listing feels trustworthy enough for practical baby use. That means the better platform is not always the one with the tidier fee line.
eBay is strongest when the audience is deeper and the item sells for more. Mercari becomes more interesting when it is easy to model and often cheaper than marketplaces with layered charges. The better route is the one that still looks healthy after you model the listing the way it would actually sell.
Shipping and Offer Pressure Still Belong in the Decision
shipping that can become bulky fast because of gear size, awkward shapes, and packaging needs on safety-sensitive items. In closer categories, that pressure can move the result more than a small fee difference ever will.
Run at least three scenarios: likely sale price, a slightly lower accepted offer, and the exact shipping setup you would genuinely use. If the listing only works in the best-case scenario, the platform choice is probably fragile.
Use This Hub To Route Into Deeper Tools
