Platform choice is workflow and risk control — not a fashion contest. Compare the parts that touch your money.
Execution path
Ask whether both platforms hit the same liquidity and account settings. A web terminal that looks prettier but routes differently can change fills. Confirm with support or documentation for your entity.
Order types and depth
Depth of market, one-click trading, pending order types, and partial-close tools differ. List the features your strategy requires, then test them under a live news minute on demo.
Stability and device reality
Mobile and browser sessions fail at inconvenient times. Have a fallback path to flatten risk. MT5 desktop is not immune; it is just a different failure mode.
Automation and journals
If you need Expert Advisors or richer export history, MetaTrader ecosystems usually win. If you need simplicity and fewer install rights, web may win. Match tool to process.
