Wikipedia does a larger size jump between h2 & h3, so even with the bold, the h3 headers look smaller than the h2 ones. Versus for us, bolding h3, makes the letters look bigger than h2.

I've already looked at various articles before my first comment. I don't see anywhere where underlining creates problems. Though you're welcome to create a sandbox article demonstrating the various uses.
 * Multimedia headers look fine. The only problem I see is the use of h4 headers instead of h3 on some episode pages.
 * Within character articles, relationships are also using h4 for some unknown reason. I'm unclear why we even bother with sections since tabber interferes with the TOC and the edit section links, making the section headers useless. (We don't bother with h3/4 headers in the Throughout the Series section, so why do we create useless headers in relationships?)
 * Within long blocks of text, underlining seems to give better emphasis to header than bolding does.
