whatever works for you best lol.
There's no definite answer as to which one is better, cause if you come to think of it, the money is fleeting with day trading but it allows you to earn it immediately, and when you pool it up against long-term trading oftentimes the numbers equal themselves such as in my case, so I couldn't really say for sure which is better and which is worse. But I know that whatever would work for the trader given his circumstances, as well as his risk appetite should be the top priority when choosing your trading behavior, so there's that.
Look introspectively first and foremost before weighing in which one's better objectively. Sometimes you'd have more affinity to day-trading, sometimes the other way around. Knowing which one you're most compatible with will make sure that you earn as much while losing less, and to top it all off, you get to play how you want to as well.
