I've been impatiently waiting to switch from
LuaLaTeX, specially because it has been stated that the latter is the successor of
pdfLaTeX (as described by Xavier in https://tex.stackexchange.com/a/126216/27833).
My question is... what is the current situation, given that they key questions are more than 6+ months old.
Is it safe to turn
lua now? Is still
XeTeX better supported and better documented? Should we keep
pdflatex for the moment?
I know the immediate answer is "depends on what you want to do", so please think of the regular user who writes reports, a couple of articles and dissertations. Nothing too fancy, just a normal guy who uses LaTeX instead of Word
Do you see any immediate problems by switching to
LuaLaTeX as of today? Most important: Any limitations? Any major advantages? What are the most biggest inconvenient of switching?
What am I missing if I keep using
pdfLaTeX? What would happen if I insist using it? Is a person who keeps using
pdfLateX getting left behind?
