Currently riding the Unifoil Hyper 150 and interested to hear feedback for wing foiling on any of the above foils. 80kg riding in 12-30 knots.
90kg, HA725 in 20 knots and up is fantastic. Can push it lower (15 knots) but it's more fun in higher wind as the take off speed is a bit higher. Once up and running it can glide through 12 knot holes easily. Little rocket ship with instant response and great glide. Love the turns on this foil. My favourite foil in the Armstrong line up along side the 925. Some killer other foils on your list though I haven't ridden them personally.

Should add axis art 799 to the mix 
And Cabrinha 800
most of these wings are better compared when sorted by wing span. Think about the span like the length of a board; generally shorter boards turn better, and longer boards worse but 2 boards of exactly the same length can still feel very different.
kujira 750 (750mm)
uni 150 (753mm)
Gofoil rs1000 (~800mm)
ART799 (800mm)
lift HA90 (~800?)
HA725 (~850mm)
Lift 120 (890mm)
CAB h800,1000,1200 (900mm)
ART899 (900mm)
Armstrong 925 (954mm)
Kujira 1095 (960mm)
Lift 170 (~980)
This should give a decent idea of the turning of these foils. Flat foils tend to feel looser while down curved foils are more locked in.
the x-factor of a wing is the airfoil section that is used. The relationship between airfoil and area will give you the stall speed, stall severity, efficiency for a given span/stall speed, and speed bias of the wing.
based on what I have modeled and tested, the kujira has the best performing airfoil, then ART, then Lift120, then Lift 90. Armstrong's airfoil isn't great. Mikes lab wing airfoil has a similar feel with better performance all around. SABFOIL is awesome at high speed but not super efficient low speed.
I don't have enough info on the CAB, gofoil, and Vyper to give a solid answer.
other important factors are overall stiffness, mast thickness, fuselage shape/diameter, tail wing design, and general balance and tuning of the foil. After testing probably hundreds of foils my top 5 wants for an everyday wing/surf foil are:
1- anti ventilation
2- stiffness
3- preferred tuning (or options for adjustment)
4- reasonable takeoff/stall speed
5- wing options
Thanks everyone for the input and for FoilAddict detailed response. Keep the comments coming. Especially interested when someone has tried multiple recent foils.
I've tried the Kujira 750 and Eagle 790 winging. For outright speed and locked in race feeling, the Eagle 790 is the best foil I've tried. For all other aspects, turning, stall speed and pumping, the Kujira 750 is better.

Armstrong's airfoil isn't great...
I'd read somewhere previously you saying that the HA Armstrongs are some of the most efficient foils on the market. Can you elaborate?
Yes they're very efficient, mostly because of their high stall speed and wide span.
for example if takuma or axis made a wing with the same stall speed and wing span it would be more efficient. Those brands could also make a wing of the same efficiency with lower stall speed and/or lower span.
What this could mean is either they picked too high of a stall to maximize efficiency or other brands are playing it too safe.
Kane, what do you mean with airfoil?
and what are your favourite front wings / wings you advice right now for different types of riders?

Thanks for the explanation, cheers. So Armstrong HA airfoil is not great in that it has been biased towards efficiency possibly at the cost of other aspects such as turning or ease of use? Sorry, don't mean to drift the thread; just trying to understand.

When you say x-factor of a foil, what does that translate to in terms of using the foil?

Please correct me if i am wrong. When you talk about efficiency of the wing do you refer to the airfoil shape that ensures the lowest stall speed for the area and span they are given?
Cheers
