It's valid best next option for those who don't run their own Bitcoin Core/Electrum server, but average user is likely to make mistake and weaken their own privacy.
How is
Wasabi without own Electrum server any better than
Sparrow without own Electrum server, though?
You missed the part where i mentioned Wasabi privacy feature. But take note i'm
only talking about how wallet obtain transaction data, not coinjoin data.
... since Wasabi Wallet 1.0 is one of very few SPV desktop wallet with strong privacy feature (Tor by default and BIP 157 implementation).
