IMO DPoS is a double-edged sword, it's better in decentralisation than PoW (this advantage may be more and more insignificant over time) and energy saving, but lack of supports from the mining industry, which is a problem for a bitcoin fork. LBTC may be regarded as a DPoS version of bitcoin, it's a very interesting experiment that no other bitcoin forks had done before or after. Time will tell us if this is a better approach.
