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.
