What’s the reason not to just go QQQM rather than VTI/VOO etc. when looking at long term ETF holds?

For just a good, basic portfolio we almost always talk about VTI or VOO for your US core and maybe QQQ/QQM as just a satellite. But long term, won’t you get better returns with QQQM even accepting the drawdowns will likely be higher in between? Maybe in the short term it’s safer, but is it really that much safer if we’re talking 20-40 years?
