well since there is no difference between the two and they are both garbage and have no demand at all, there is not much to choose from! and so far in the past couple of years we have seen that they keep changing the name of the tokens but in the end they are only serving one purpose and that is fund raising for the owners and then death. i have not yet seen any token that could deliver at least 10% of what they have promised. they just get pumped, some big pumps like 100% and then die off.
How about Binance Coin (BNB)? Whenever I wanted to look at the potential of utility token, I always look at BNB. The coin's utility in Binance ecosystem has definitely boosted the underlying value of the token. Their price graph is consistently up, which shows that utility tokens have a shot in the market.
As for security token, I really can't see any function, aside from representing security (ownership) in digital form.
