Do webcontrols have any disadvantage over html server controls?
<p>I just thought I should ask because It doesn't make sense to me that both versions exist. Is this just for compatiblity with older HTML programmers?</p>

<p>They both can do the exact same thing when runat="server" is set, right? Unfortunately my book on the subject does not really elaborate on this, and I couldn't find anything on Google.</p>

<p>Is it possible that webcontrols are slower because they "wrap a little more"?</p>
