Not really, just because they're selling order flow doesn't necessarily mean the customer gets a worse deal. Robinhood still has to follow reg nms, they have to fill you at the NBBO.

But is their NBBO worse than other firms (worse routing options)?

That's literally a contradiction. Look up what NBBO actually means.

It's actually more complicated, nbbo governs quotes but there are a few other things that affect your actual trade price such as exchange fees and price improvement.

For example, every exchange can have the same quote, but a different liquidity fee.
