What's the shape of those 9070 hoods like? Do you have any experience with the 7970 or 6770 DI2 levers such that you can compare the shape? If so, can you also comment on the increased feedback the 9070 shift buttons are said to afford? Is the tactile sensation of clicking one of the buttons that much different from 7970 or 6770.
As far as mechanical feel, I can't tell a significant difference. Maybe its different if you ride with them but I cannot tell with them off the bike. Can't say either whether one feels more ergonomic over the other.
I can say that the 9070 levers are a bit smaller to wrap around. And they are noticeably lighter. 115 g vs 156 g. The dimpled di2 button is just a bit longer. Other than these differences, I'd say they are very similar.
The Alize headset has been touchy too between too much pre load and than slop. I wonder if this will take a set after some road time.
As they say, a picture is worth a thousand words!

9070 is very nice, super smooth and solid. I do however get a little noise in the 23 and 25 on my 12-25 cassette. Same issue as mentioned in previous posts - I'm not sure?
I weighed mine too for comparison. Over claimed but they ride really nicely. Bladed spokes are much more side wind prone than 7850 C50 and C24 but you quickly get used to them.
Total: 1360g (1260g claimed)
Strangely the rear was almost the same weight as the WH-7850-C24-TU I took off whilst the front C35 was 108g heavier than the C24.
I've had 2 short rides on my 9070 and I like it so far. Hoods feel very similar to my old 7800. My cassette is 11-28 and I get a strange noise in the 28. Almost like the front mech is rubbing for half a turn of the pedals. I have the same block on another bike with DA 9000 and there is a similar noise...
Shifting the Di2 with full gloves on can be a bit hit or miss until you get used to it. Without gloves you can feel the junction between the two levers/buttons and it not an issue to press the right one.
With thick gloves on trying to 'press' the buttons isnt easy at all as you cant really feel where they are. An alternative I'm using is to try and roll your hand forwards or backwards to shift, seems to work for me, again after practice!! Eerily silent shifting with no mechanical feedback takes some getting used to too!!
