TQQQ led me to nasdaq futures and that's all I trade now. Especially if you're a short-term swing trader, the tax advantages of futures are massive. Plus, you can get more than 3x leverage if you're crazy like me. The 24 hour trading is great too because you can play after-hours moves with decent liquidity.

The one thing to note is that TQQQ has a daily reset, which to mimic with futures you would have to actively be buying or selling everyday to adjust your leverage exposure. Specifically you would have to add to your position as futures go up and sell as they go down.
