Which HIMEM.SYS works best?

[Howard Schwartz]

Now that we know there are versions of HIMEM.SYS that take up less
disk space and/or memory, does anyone have a clue whether the later
and larger versions of the software actually manage memory better?

In theory, the extra bytes are not there for nothing, although I
would not bet on this since we are dealing with Miscrosoft. I would
love to use an equivalent program that really does the same thing
but uses less memory.
