One basic reason for why CharSequence is better, is that a StringBuilder is a CharSequence. Right now, I am constructing a message with lots of ifs-and-buts, and then when I want to log it, i _have to_ do .toString() on it, creating a new object with a new char-array.

But the other is what OP mentions: You might want to pre-allocate log char arrays for a thread, and then reuse them - avoiding object creations. This would actually work nicely with StringBuilders, using setLength(0) to "clear" them.
