shorting SPX or buying SPXS

I am familiar with shorting as well as buying SPXS although this was due to temporary hedges during big events such as CPI or FOMC. I am not however too familiar with the longer-term fees, such as a month or two out. How do borrowing fees stack up against inverse ETF degradation? I am genuinely asking, I know I could probably figure it out on my own with a quick google search but I much prefer detailed personal insight.
