Which is easier for new players to learn, SR2 or SR5?


Of the many editions of Shadowrun, we have access to the second and the fifth one. The group we’re considering SR with has a few rather inexperienced, newbie players (and some who played a lot of SR2 but have just started reading SR5.)

Which Shadowrun edition’s mechanics are more welcoming and easier to learn for relatively new players, SR2 or SR5? Why? Please, illustrate and explain briefly.

(SR5 seems more up to date, obviously, yet it also seems way more complex, the core appears to be chock full of not-really optional rules.)
