I like both Pchain and Eden. Pchain has rich tech features and deep rooted in china, while eden is doing things pramatically and very business oriented. Here is a great analysis I read on eden which explains how eden is different - https://steemit.com/edenchain/@acwtkae/edenchain-a-practical-next-generation-blockchain-embracing-the-deep-blue-ocean
Which business you mean? I think Edenchain is just a copy of Korean blockchains... (Icon, Hycon, Yggdrash etc.)
While Pchain is really oriented for business with their chiclchains and they have most higher TPS right now (around 180k TPS) while their competitors Quark and Zil have much less...
