Why would I ever use Starkware?

I've been looking at zk-rollup based layer 2 solutions and obviously came across Starkware and noticed:

– proprietary software

– 8 billion dollar valuation

– no plans for a token (if there would be one it would most certainly be a VC dump given how much VC money it has)

– no native evm compatibility

Meanwhile ZkSync is basically the opposite, have plans for a token, open-source, decentralized, etc. They also seem further ahead in zk development than anyone else including Polygon or Loopring.

Why would I ever choose Starkware over ZkSync?
