Good point, indeed Monero has many technological advantages over other vague Altcoins, not only in Privacy (especially since it was proven that the Monero private tx ids could be easily reversed engineered: https://eprint.iacr.org/2017/338.pdf), but also since it was one of the first coins to introduce innovations such as dynamic block size, which improves the perspective for long term scaling, which I reckon, is the most important part about cryptocurrency.
Since, as Andreas M. Antonopoulos said (here's a nice video of him making a point https://www.youtube.com/watch?v=SMEOKDVXlUo&t=1s), we are now only approaching the verge of the dawn of the era of blockchain and cryptocurrency.

However, I would like to note, that by default, any crypto to crypto exchange transaction using an exchange service (which has a properly configured combination of hot and cold wallets) will equally conceal the public key (wallet ID) from which the funds were sent.
