I liked position 1 the best, followed by 2, 4, 5, and 3.
For me, I want to love position 3 so much, it sounds so good alone - deep, rich, thick - but without EQ (or with EQ the same as other positions), it can disappear. Live, I normally add quite a bit of mids to position 3 to pull it back out of super scooped land. I think the video demonstrated that and what I've ran into playing the 5HH (I only listened on iPhone ear buds).
For the other positions, I think the 5HH does a great job of getting close to other types of bass tones like P and J. I've always thought that position 5 got close to a P tone (others seem to like position 4 for that) and thought your video demonstrated how well that tone can fit.
For position 2, I think you're in jazz territory, but I like what an actual J bass does so much better than position 2. I've been playing my Lakland DJ5 jazz a lot more while demoing the 5HH and it got me to remember how much I really like a good jazz bass tone (so much so that I think the DJ5 is getting thrown back into the gig rotation rather than taking two SR5s like I normally do).
Your bass sounds and looks great though and ultimately, it comes down to whatever you like and gets the job done for you. Great vid, thanks for sharing!
