The bitcoin community truly believes that bitcoin mixed with the xmr ecosystem could beat any crypto ever created? Even bitcoin!??
For privacy purposes, the best option is to use only Monero.
If you want to get bitcoin but still keep your privacy, it's a good idea to swap bitcoin to monero and back then but it will be completely meaningless if you do this immediately. It's best to convert bitcoin to Monero through one DEX, then swap this monero to Bitcoin again through different DEX but keep in mind that if you circulate 1BTC back and forth, you might be compromising your privacy. It's better to have at least two receiving address with different amount of coins.
Let me make this clear for you that no created coin that exists that is better than bitcoin. If you want privacy, you can go for monero. But you should know that there are other ways that you can go for like using coinjoin, mixers and swapping
One should be very careful with coinjoin and mixing too. For example, it's not recommended to coinjoin through Wasabi. Also, one has to keep in mind that one might get in trouble if receives money from a mixer with a bullshit AML score.
