It really depends on the type of experience you want and how you'll be promoting it.
If you want to make a "shop" that looks how you'd like then Shopify is probably best.
If are just looking for somewhere to send people for them to buy, then a simple service like Big Cartel would be good.
And if you don't already have a clear sense of who would be buying them and would need people to discover your products on their own, a marketplace like Etsy is best.
