IOTA because:
The "Tangle" allows for zero fee transactions earthwide (micro & even nano payments)
Tangle architecture superior to blockchain
Extremely fast transactions (nearly instant)
Network gets faster with more users (Unlimited ceiling - already faster than Paypal,Bitcoin, Dash, ETH..etc)
Decentralized (Optional operator, which will be removed soon, when network can selfsustain)
Scales for the IoT (M2M transactions)
No miners & no third parties
Fair token distribution
Very limited supply of tokens (comparable to btc satoshi)
Quantum secure (Immutable)
Interoperability
Pushing real world adoption
Strong community (13.000+ active members on slack alone)
Iota Alliance (Amazing group of developers & highly qualified scientists)
David Sonstebo, Dominik Schiener, Come from Beyond, Serguei Popov (Founders and genius behind Iota)
Recent Partnerships (Ubuntu, Cisco, Microsoft, Medtech, Huawei, Bosch, Alpha, IBM, Gnosis, Luxoft, F6S, Satoshipay, Filament, Medtech, Slock.it, Foxxconn, IDEO, Harward Medical School, Procivis, Berkely, Seedlab, Mooti and many more.
THIS ^
let me fix this part
Very limited supply of tokens it is a non-inflationary token but there may be stock split which is not same as inflationary. (main purpose for stock split is to better focus on machine 2 machine automation + nano transactions)
stock split means to give a certain % increase to all accounts/holders and everyone will receive exact equal portions in %, which means it will not effect the price of your holdings.
what it will mean is that you/machines can spend 0.0000000000000000000000000000000000000000000001 cent of value (subject to the total % of stock split) . ultra nano tx.
