FreeDoom mentions that ZDoom is recommened, and is apparently the target program it is designed for.
ZDoom seems to have more recent activity than Legacy, which might lead you to think it was the newer program.

I tried ZDoom on Linux and found that it is very anchored in the original Doom controls and appearance.
ZDoom does not have the freedom to change controls, you are stuck with the original mouse behavior.
ZDoom does not have jump.

ZDoom does not have several of the bugs that show up using Legacy
with FreeDoom.   Level 13 works in ZDoom.

I prefer to enhance the playability, as Legacy is doing.  I do not see
the need to keep the old behavior if it cramped the playing.  Some
puzzles in the game may solve differently, like being able to jump up
and grab something rather than find a contorted way to get to it.

I have also submitted some patches to control the door speed delay.
Some of the doors (over switches) close too fast, so that even after 20 tries I cannot get to them to push that switch.  keeping the original behavior in such cases is no fun at all.  I am just forced to to cheat.
Now I just change the door delay to x1.5, and I can get to those
doors without using cheat codes.

The console in Legacy is the best idea.  ZDoom just uses the original Doom cheat codes.
