First of all, both anime share a common theme, and that theme is video games. Both anime have action, adventure and fantasy genres, and both main characters are high school VRMMO players. Compared to the Sword Art Online anime, SLF's plot is a bit more conventional, but it's also quite unusual. If you have watched SAO and liked it, SLF is the anime for you, but if you liked SLF, I recommend SAO. Finally, I would like to add that when I think about what SLF has that SAO doesn't have, I think of comedy and more action.
Simply 2 very pleasant anime about full dive VR MMORPG worlds. Meanwhile SAO is more focused on survival of the characters and some drama connected to it, Shangri-La Frontier is focusing more on jokes and stories of individual characters than world story at first place.
