This article tested various bullet types & found that plated bullets generally are the slowest.

In the recent .45 Auto Rim +P article (Handloader #306), the 230gr Speer Gold Dot HP (plated) was slower, across the board, than the 230gr Hornady XTP (jacketed) using the same load in the same pistol.
Example: using 8.5gr/Power Pistol the GD clocked 1011 fps vs the XTP's 1032 fps.
