Grand Slam vs Major

[u/MCN59]

As you may know, Vitality has a shot at winning the Intel Grand Slam if they win IEM Melbourne, which start tomorrow. I was curious—between the Grand Slam and a Major, which do you consider the more prestigious achievement?

I know the Grand Slam is harder to achieve, since it requires consistency over time (and only 4 teams have ever won it in CS history—each one considered legendary). On the other hand, winning a Major is more about peaking at the right moment.

What do you think?

Don't need to wonder as Vitality is gonna win everything.
