Die hard anniversary vs legacy collection

[Goose Pants]

Which is the best version? Or should i buy individually?

[My Other Self]

There is no best version. The discs are identical -- the Legacy Collection just has the abysmal fifth film included whereas the Anniversary set only has the first four films.

The 25th Anniversary set comes with a bonus disc called Decoding Die Hard. That's why I bought the anniversay set along with already having the 5th movie on bd but honestly I haven't even watched much of the extra disc. If you want/need all 5 movies plus the bonus disc they will all be included in the Nakatomi Tower Ultimate Edition coming out in a few months.

So:
25th Anniversary: Die Hard 1-4 plus bonus disc
Legacy: Die Hard 1-5 no bonus disc
Nakatomi: Die Hard 1-5 with bonus disc and unrated version of Live Free or Die Hard
