A single TermQuery is surely the fastest query of all. But, what
are you really trying to do? It is not generally useful to index
things untokenized except for precise key-like fields but not for
full-text ones.

If you index "A Phrase" as untokenized, you would find it with a
TermQuery for "A Phrase". You must use exact case. If you're using
QueryParser, the text get analyzed and most analyzers lowercase. If
this expression is quoted it would become a PhraseQuery with two
terms, or if it is unquoted it would become a BooleanQuery with two
TermQuery clauses - either way it would not match if you indexed the
phrase as untokenized.
