Well, if those are the only pros, i would think..
The small blocksize is just cause btx is a new coin.. Also bitcoin, 6 months after born had a small size blockchain.
And the fast transactions depends.. We will see when/if btx will have a large user-base, also many people think that larger blocks are bad.
Tons of coins out there has these and more valuable things.. So until now i'm not reading a decent motivation to choose btx
