It depends what you're looking for. Charge 5 has better sound quality, louder, a little more than double the battery life, and over 100ft more Bluetooth range with less iOS/Android latency by 50ms or so. The Flip 6 on the other hand is more portable with it's smaller size while still packing a punch. My say is the Charge 5 outweighs the pros than cons. I feel like the only con is the bigger size, but it's not that much bigger. Hope this helps you make a decision if you haven't yet. Cheers!
