So for now I'll likely shed the RSP and replace it with more QQQE, as I'm indeed a bit lazy, and don't want to deal with anything very complicated.

That would be a logical idea based on my comments about relative valuation. (to the extent they have any value!)

But...
Keeping to the theme of the brilliance of laziness, you could also leave well enough alone.
RSP isn't going to go bust. It pays a dividend. It will be worth more over time quite predictably, and will be priced higher in 5 or 10 years.
If it's a little overvalued today, what's the worst case? A dip, which is normal anyway, and maybe net nowhere for a few years?
If you're reasonably well off (don't tell me), maybe that's just fine. It may not really be necessary to try to second guess it as a pick. You could just let it sit.

Mr Buffett's advice for his wife is to hold mainly the S&P 500. She will be very rich, so the dividends alone will definitely be enough whether it's wildly overvalued or not.
For some of us, we might want or need to be a bit more aggressive because we need a decent long run real positive return for many decades.
But not always. If your portfolio is comfy enough and/or the time horizon is not that long, there is no requirement to sweat the portfolio to eke out that extra couple of points.

Just a thought!
