I'll take this line by line...

The Midas is supposed to have better sounding preamps. I haven't heard it, so I don't know.
Pres between Midas and Si Impact are probably comparable. Both better than X32. Tied.
SI has more knobs to twiddle...X32 seems to rely more on the screen.
The controls are easier to visualize. Less screen reliance is better. You can run the all of the Sis WITHOUT the screen if you have to. They feel more analog... they're much faster. The X32 screen is several layers deep and the interface is confusing. Si Wins.
SI gains a touchscreen, but the screen is smaller than the X32's.
You don't need the screen during mixing, though, only for setup, patching, save/recall, etc. Not a big deal. Tied (Being generous, I like the SI interface better).
SI has less accurate metering.
Ok... but who needs meters for anything more than seeing that a channel has signal and isn't clipping.. Si's meters are set up for just that. Less to look at... red is bad, green is good, yellow watch out. Easy.
Tied.
SI has 14 mix busses, 6 of which which can be stereo, X32 has 16 (can be linked to run stereo).
SI also has a dedicated mono out on the FOH mix which is great for a sub feed (doesn't eat up an aux). On X32, linking mix busses takes up two busses. On Si, those six busses can be assigned to stereo outs, so you still have 14 busses. As soon as do 2 stereo busses on X32, you've got less mix busses than Si. Si Wins.
SI has 4 EQ bands, X32 has 4, but 6 on Mix Busses.
Si has a 30 band graphic on ALL outputs. The GEQs flip to fader in two banks that are always the same, and easily accessible from the main panel with two button presses. X32 has only the 6 band parametric, plus a few assignable GEQs (not enough to do mains and 6 monitor mixes IIRC). X32 GEQ fader flips suck. They're hard to access, and take a lot of time... more than to just use the screen.
Si Wins.
SI has four stereo Matrix busses, X32 has 6, but can link them to stereo.
Depends on what you need... I've never needed more than 4 and having the option to do stereo or mono without eating up matricies seems to be a bit of a win to me...
Tied
SI has assignable fader layers, X32 has split in/out design.
This is purely a matter of preference. X32 has more workflow options, Si has better layout capabilities. The one thing you can't do on SI is see one channel in every monitor mix at the same time. Some people like to work like that, I never have used it when I've had it. Again, I like the Si way better, but we'll still say
tied.
SI has glowing faders (eye candy), X32 has better LCD Scribble Strips.
Si Impact has scribble strips... who cares if they have a picture on them or not. Glowing faders are WAY more than eye candy. They let you see Inputs vs Busses Vs FX vs GEQ very easily, and you can easily tell if a channel is pre or post in a mix. This feature reduces moving the wrong control without realizing it.
SI has 32 inputs onboard (the 40 channel count includes assignable effects returns), X32 has 38 inputs onboard (40 if you count USB). X32 adds 6 TRS inputs and 6 TRS outputs onboard.
Six of those X32 inputs are line level only.... limited usefulness. Si Expression/Perfomer has more inputs available by adding stageboxes. This is hard to call...
X32 beats impact (by a hair) Si Perfomer beats M32 (by a long shot... 96 channels available IIRC)
SI currently only runs on IPad (but will likely change), X32 runs on IPad, Android, Linux, Raspberry Pi, etc..
Meh... it's a tool.. buy whichever one you need.
Tied.
SI is slightly smaller than X32.
OK.
Si wins.
SI has optional card slot, 32 ch USB and 32 ch for digi snake (or no USB and 64ch digi), X32 has 32ch USB, 2x 48ch digi snake ins, plus 16ch out for personal monitoring.
Si Impact comes with the 32/32 card. Expression and Perfomer come with no cards... Perfomer has 2 slots though. Behringer's personal monitoring system is a joke and a pain... have you ever used it? I have. You're better off just to run feeds to headphone amps and let people adjust mixes with their iThings. Much cheaper, more control. And Si can do that too....
Tied
X32 is $100 cheaper (thru NSL) and can be bought used for much less.
$100 is a small price to pay not to have
Behringer stamped on your device.
Si Wins.
They're both really, really close. I've got an X32 Rack, and a full X32 @church and love em both, but I'd likely be just as happy with an SI.
They're good at different things. Si is better in many ways... X32 does do a FEW things Si doesn't... but in doing so it tends to complicate things dramatically. I like Si WAY better than X32, and I've had enough time on both of them to evaluate them well.
