gameplay comparison

I have yet to play halo 5, and was wanting some insights into how it compares with previous halo gameplay. I dont want a nitpick, but an overall comparison between say:

halo 4 on MCC (no ordinance)
Reach on Zero Bloom mlg settings.

i ask because i was just goofing around with my kids with the zero bloom settings and was surprised at how much I still liked it.
