What platform to buy GME?

I'm curious to know, for those seeking to invest in GameStop's (GME) stock, which platform would be the most suitable? Given the recent fluctuations in the market and the influx of retail investors, I'm particularly interested in understanding which platforms offer the best user experience, lowest transaction fees, and robust security measures. Additionally, are there any specific platforms that cater more towards retail investors, providing educational resources and community support? With so many options available, it's essential to make an informed decision to ensure a smooth and secure investment experience.
