Conclusion

Summary
MEXEM offers a lot of products and functionalities. Their platform is quit extensive, but can sometimes be overwelming for new investors. Prices are reasonable, but for small investors the USDEUR conversion can be pricy.
Trade Republic provides a seamless, commission-free trading experience with an intuitive mobile app that's great for beginner and casual investors. However, its limited asset variety and occasional delays in customer support may be frustrating for more advanced traders.
For beginning or ETF only investors Scalable.Capital is an easy to use platform. But there are some limits, it is not possible to place orders in USD for example.
