Wilder is a good manager but this is laughable. Every achievement Wilder has done, Howe has done better, for longer.
Howe took over Bournemouth in League Two. Took them up to League One. Left for a bit to totally rebuild Burnley (who got promoted 18 months after he left). Returned to Bournemouth in League One, took them up to the Championship and within 2 seasons was promoted to the Premier League, where he's kept them.
Like Howe, Wilder has took Sheffield United from League One to the Premier League - an achievement which deserves praise. But he's only been in the Prem for 14 games. If he keeps Sheffield United up comfortably for the next 3 or 4 seasons, then he's possibly at Howe's level.
