Reach:more content than halo5 destiny bo3 at 10g!?

yep I said it, I may be wrong but it sure seems like it.

the games in this generation requires over 50 gigs of data with an underwhelming amount of content. imo the amount of content in Halo5 is only about 10% of Reach. for an example we have arena and warzone btw and weekly standard playlists in halo 5.

reach has:

matchmaking coop campaign
matchmaking firefight
btb
arena
multiteam
rumble pit
doubles
team objectives
super slayer
living dead
invasion
MLG
griffball
score attack

also:
psych profile
file share forge
entertaining campaign
gorgeous maps

all this, 10 gigs in Reach? I played Reach at release under a different profile, now I decided to play it on xbox one and was thinking about purchasing all the add-ons again. does anyone here think Im making a good choice with this? I know it sounds strange because I had all the dlc before on 360 with different profile. Im so bored of halo5 and hope many players are still playing dlc from Reach because Reach is more of a completed Halo game imo.

Halo Reach is amazing however nowadays it have become a custom game paradise, matchmaking has many to choose from and clans that spam messages still. All in all its worth more to me than halo 5 ( I purchased it and returned it the same store trip).
