So we are torn between two equally potent arguments. If you want/need latex-preview, forget about lualatex, but then restrict yourself to character sets it handles and forget about fancy utf8 support. If you want/need utf8 support, forget about latex-preview and compilation speed (at least FTMB)
Let's hope that the developers focusing on lualatex produces the speed improvement we need for lualatex to be a reasonable backend for latex-preview.
