Is it better to buy BTC or BCH?

I'm a bit torn here. On one hand, BTC has been the original and most well-known cryptocurrency for years, and it has a solid reputation and a large community supporting it. Its price has also seen some impressive surges over time, making it a potentially lucrative investment. But then, there's BCH. It's a fork of BTC that aims to solve some of the scalability issues that BTC has faced. BCH supporters claim it offers faster transactions and lower fees, which could make it more practical for day-to-day use. Plus, its price has also shown some promising growth. So, which one should I choose? Is BTC's established reputation and potential for big gains worth the potential drawbacks of scalability issues? Or, should I go with BCH for its potential in terms of practical use and transaction speed? I'm really not sure which way to lean. Any advice?
