You can also use HLG without a LUT, which I do.
As I have never use Vlog, I can't say how hard or easier it is to grade, etc.
Though, I have no problems using it Resolve.
Captured from another forum:
"Yes, HLG is available with 6K anamorphic mode.
In another note, besides Paul's excellent HLG LUT, you can also use HLG natively with Resolve 14 for Rec 709 delivery:
- In Project Settings, under Color Management, Change to Davinci Color Managed
- Under Color Management select:
-- Rec 2020 HLG ARIB STD-B67 for Input Color Space
-- Rec 2020 HLG ARIB STD-B67 for Timeline Color Space
-- Rec 709 HLG ARIB STD-B67 for Output Color Space
In this way I am getting quite similar results - I haven't compared color accuracy, etc, but in general both look georgeous.
Paul's LUT has the advantage that it can be used when the project is not color managed in this way, so you can mix and match footage"
