Head-to-head comparison across ratings, fees, asset coverage, and platform breadth.
4.0 / 5
For active day traders and short sellers with $27K+ in capital who need multi-source HTB locates, true DMA without PFOF, and a human picking up the phone. Not a fit for buy-and-hold, beginners, or anyone who wants a polished mobile app.
4.2 / 5
Best for cost-conscious active traders who want $0 options, free Level II, fast routing, and broad crypto coverage. Educational depth and fixed-income shelves are thinner than the full-service incumbents.
