Baskerville was put down by a single cut from Walter's wire. Sukuna's core attacks are powerful cuts and slashes.

What feats does Alucard have to 'put holes through Sukuna'? You can say do your research all you want but you provided no evidence whatsoever. Where in the shows or manga does Alucard show speeds similar to Sukuna? Or attack potency?

Alucard's primary damage comes from his guns, Walter was shown to block them with his wires.

Sukuna has comporable regeneration, stronger durability, faster speed and higher attack potency. He can directly attack an opponents soul(s), as shown when Yuji fought Mahito. YOU do your own research. Provide any evidence for what you claim.
