Facebook lite app requires less space, uses less data, loads much quicker and consumes less battery than the facebook app. Still it doesnt spoil the fun of using facebook also. Lite app is more suitable for people using 2g and unstable networks. The app loads seamlessly in these conditions also. The app doesnt irritate you with the the message to install messenger. Now thats good. Moreover its easy to use. And the best part, it requires only about 5mb storage space. I prefer facebook lite to facebook app.
