Hello there, long time lurker, first time poster!
My Qui-Gon arrived today and I would like to give my thoughts and show a few photos.
Here he is next to the Hasbro version. Checking Qui-Gon's height on Wookiepedia, the Hasbro version is in perfect scale. The SHF Qui-Gon is somewhat too short.
When it comes to accuracy, the tunic colors of the SHF Qui-Gon appear to be correct and the Hasbro version is off here.
The belt is not screen-accurate, on neither figure. SHF Qui-Gon is missing some of the cylinders to the left (his right), Hasbro has them. Hasbro Qui-Gon is missing all the cylinders on the right (his left) however, and SHF included them. The rivets on the belt are a little too close to the buckle on SHF Qui-Gon, but no one will probably care.
The Hasbro Qui-Gon has a belly, they sculpted his tunic so that it bulges above his belt. Liam Neeson did not have a belly in Phantom Menace and the SHF Qui-Gon has no belly or unfortunate creases in his clothing.
The back of the figures. You can see SHF returned to the golden hair of earlier figures, it's quite pronounced in photos, less so in hand.
The side view, you can see how much shorther SHF Qui-Gon is. The gap in SHF Qui-Gon's head is not very noticeable, it doesn't bother me. He doesn't come with an extra head but with an extra face.
The face sculpts. SHF Qui-Gon is much better, in my opinion, Hasbro is quite off here. The SHF Qui-Gon has a younger appearance, but this is a 6 inch figure after all and it would be quite difficult to sculpt tiny wrinkles around the eyes etc. If only his hair was more brown and less gold. It's not as noticeable in normal lighting conditions.
And now with SHF Obi-Wan, Obi-Wan has more or less perfect scale, his SHF Master is taller than him, fortunately, but Hasbro Qui-Gon shows how tall he should really be.
However, SHF Qui-Gon has dropdown hip joints. And with his legs fully dropped down he now has the same height as the Hasbro version. Proportions are somewhat off now perhaps, but if height is your concern you can just extend his legs and everything is perfect.
Qui-Gon's alternate head is very scene specific, but it works and looks quite good within that context.
All in all Qui-Gon is a very nice figure. In standard configuration he is somewhat too short, but that was to be expected since SHF likes to underscale taller characters. Drop down his hip joints and height is perfect though. His hair is of a very soft, rubbery plastic and very pliable, you can easily turn his head and rotation of the head is really good.
The Hasbro version is not a bad figure, if only the face sculpt was better. But in direct comparison it looks like a toy and the SHF Qui-Gon like a collectible. You see the difference in quality immediately.
Btw. Qui-Gon's lightsaber is different from the one we got with Obi-Wan. The handle seems to be identical, but the blade is a little bit longer (maybe 2-3 mm) and has a somewhat different color. The original saber is a little more green.
If someone is still on the fence about Qui-Gon I would recommend getting him, he's a much better fit with SHF EP 1 Obi-Wan than the Hasbro version because of the very different aesthetics and overall quality, even if the Hasbro figure is by no means "bad". It's sturdier, heavier and has perfect scale. But looks like Liam Neeson's stuntman.
