Yep good insights. Anytime you add an effort toward decentralization it's harder and harder... steem-engine will keep developing cool new features at break-neck speeds and SMT development will always be a bit slow however in the long run what we really really should be hoping for SMT.
But splinterlands tokens like DEC,Beta,Alpha have been perfect examples for steem-engine. Peakmonsters has a token just to basically issue a ticket to tournaments and steem-engine has a perfect product for that.
So in the end i'm super happy both will some day exist together.
