Yes, a uniform distribution provides better security, but it must be over a large enough character set. In your examples, what is the character set? Is it just one or two characters ("m" and "_")? If so, the distribution may be uniform, but the character set is too small - and that is the problem. If the character set is larger (e.g., all letters and underscore), then your distribution is highly non-uniform - and that is the problem.
