The transaction throughput of NEO is measured up to about 10,000 tx per second. Right now the transaction throughput of NEO is said to be 1,000 per second. We all know that the transaction throughput of ETH is only 15 tx per second. Does it mean that NEO's tech is better than that of ETH?
Technology simply cannot be measured as better or worse in every case. Transaction speed is just one factor, and if that were the case, then VISA has better technology than any crypto on measure of speed alone. In a more specific look, the ability of a crypto network to scale according to growth/usership is the measure of how flexible and agile the technology is. Bitcoin has its problems, but not because of tech, because of the design of upgrades. ETH has less problems because leadership is clear and accepted (they also have disagrements, however!).
NEO we can only judge if and when the network ever gets to a size it needs to scale.
