In conventional English usage, acronyms always use upper-case. All
other coding conventions deal with that situation gracefully (or at
least not terribly). If someone strictly follows the coding convention
you might end up with a weird identifier (m_tlaThatDoesSomething,
m_tLAThatDoesSomething, ...); if they favour English over coding you
get (m_TLAThatDoesSomething).

The leading underscore is unique in turning that last case into
something that violates the language standard, and for me that's
enough to eliminate it from contention. I strongly discourage its use
in any C or C++ project.
