Currently using S3 for storage of mp4 videos and bunny cdn on top of it. Should I use Sippy and move assets to R2?

I’m getting an 85% cache hit rate with Bunny but I still spend $500 a month on egress from S3. Sippy sounds great but says it’s not for production…also, does it make sense to use it between S3 and Bunny at all? The videos are played by my own embedded video player.
