A few things that set it apart...
1. Mimblewimble protocol. I can think of only a handful of MW coins. MW protocol stores the end state of where coins are and NOT every transaction. As a result, the entire ledger is tremendously scalable.
2. It can be mined with three different algos. CPU mining on RandomX, GPU's on ProgPow and ASIC mining on a cuckoo variant.
3. All coins are completely fungible. It is impossible to have 'tainted' coins. One cannot be distinguished from any other.
4. Privacy is a default rather than a selected feature
I am sure others can chime in. Those are the highlights as I see it.
