In a nutshell, I recognize SilentPayments' potential with its intent of merging the anonymity that Coinjoin today somehow differently provides and the reusability of a single address that has been proposed with PayNym BIP47 currently implemented on Sparrow Wallet.
Silent Payments doesn't have any similarities with coinjoins, it's just a way for the sender to generate a new address for the receiver (non-interactively). BIP352 is a huge improvement over BIP47 for this though.
Yes technically yes, for the end user, that only aim to increase its privacy somehow, it could be comparable. The main issue is that not all users understand to these details the differences between all the BIPs/features.

Silent Payments doesn't increase privacy though, it's just a UX improvement that eliminates (half of) a round of communication between the sender and receiver when a new address is generated. Basically, it's BTCPay Server on steroids.

This knowledge gap was the huge problem with BIP47 that BIP352 fixes:
BIP47 Paynyms require the sender to have an understanding of how blockchain analysis tactics work, and then manage UTXOs carefully with labels before and after sending multiple on chain transactions.
BIP352 Silent Payments eliminate this clumsiness and the extra on chain fees. The only tradeoff is a heavier scanning requirement.

Noted, hopefully there will be some workarounds sometime soon
