SPYI vs SP500 which is better?

I’m debating thinking about where to put some money. At this point in time, the market is as all time highs. Many financial experts say the market may start going sideways for a bit. It may not increase 8-10% like it has been because of how over inflated a lot of stocks are. Assuming the market goes sideways or even continues going higher by less than it has been (3-5%)I think parking money in SPYI is the smarter move. Because spyi will continue appreciating (only if the market does) and paying the 10%+ divided. If the stock market stays the same, spyi definitely will be the better move because while the market is not going higher, I will still be receiving the dividend. Do you guys agree with this thought process?
