The only thing weird here is that if you use the same tool to see fees on which network is higher, you get a different results.
I tested it in Electrum (testnet): it recommended almost 50 sat/vbyte, which puts it 0.66 MB from the top. When I tried 20 sat/vbyte, it got 130 MB from the top. With 10 sat/vbyte, I can't even broadcast it.
At least testnet has the difficulty adjustment thing, so once in a while it processes a lot of blocks to clear the backlog. But other than that, it's more congested than real Bitcoin.
