Since you're looking for the best. I'll be pointing out the
BEST for the variety of different content production styles.
GAMING (console)
Any current-gen console; PS4/XB One.
A separate microphone; Either AT2020 or Blue Yeti, both are praised by large YouTubers.
An external capture card; The Elgato is your best bet.
A laptop to record the feeds; Something with an i5 minimum and at least 1 TB of storage.
[Looking for an editing PC? That's doubled with the gaming PC]
Vlogging
Canon 80D, or any current major camera with articulating screen AND a hotshoe mount.
Shure VP83 or Rode Videomic Pro; Shure takes AA batteries, Rode takes 9V. (I vote Shure)
Lexar 1000x 128GB SD card (you can get a 2 pack pretty cheap on Amazon, but never spend more than $1/gb)
Joby Gorillapod (for moving around)
Manfrotto tripod [pick one] (for talking head)
PC Gaming / Editing.

Powerful enough game and edit for yeaars to come and more storage than you'll ever know what to do with.
(offline backup of videos perhaps?)
