Just wrote a detailed article on reddit based on technical comparison between NEO and QTUM, sharing it here:
So here is an unbiased evaluation:
NEO pros over QTUM:
NEO has its own blockchain. QTUM uses Eth vm.
If there is a bug on NEO blockchain the NEO devs are not dependent on anyone else to troubleshoot the code. If QTUM has a bug in the Eth vm, they are dependent on Eth devs to troubleshoot the code. Qtum devs can troubleshoot the Eth vm code, but troubleshooting someone elses' code is very tough.
NEO scaling is the best in the business right now. (Over 10k tx/sec). Meanwhile QTUM, which is using Eth vm has the same scaling issues as seem by Eth.
Ease of collecting GAS, even offline.
Non technical pro: There are a lot more quality ICOs and Daaps scheduled on NEO in the next year.
Cons:
NEO is highly centralized right now (I know in 2018 NEO team will be working on decentralizing). Its nodes are centralized, and have gone "offline in the past".
Achieving decentralization will need people to run full nodes. But since GAS can be collected by NEO holders even without runnign a full node, how would the NEO team incentivize people to run full nodes?
The scaling for NEO is one of its major pros right now, but every blockchain is working on getting to millions of TX/sec. (EOS, Eth, QTUM ADA etc). There is no clear roadmap on if there are any SW enhancements to the NEO blockchian in 2018 (other than trying to achieve decentraliztion). Would hate to think NEO has peaked wrt to SW enhancements to its blockchain.
Let me know what you think, and let me know if you have more info on some topic I mentioned.
