Your confusing deep dof AF hits with a 7d vs shallower dof with the 5d
One can adjust the 5d to deeper dof but usually we're not
The best lens for crop is 17-55 f2.8 IS which is the FF equivalent of 27-88 F4.5 IS for over $1000 -- deep dof - but wait - FF'ers can get 24-105 F4 IS L
F2.8 on FF blurs the backdrop but F2.8x1.6= F4.5 dof has more clutter
So your statement is bias because a camera body cannot take one shot - it takes lenses and Canon has intentionally not developed lenses for crop and kept the differential to be deeper dof with crop and noisier at hi iso
There is no match on crop for the shallow dof that the primes can give. No match for L primes.
So when one perceives greater AF hits, what was the dof difference between the two formats?
I haven't missed a toss or a kiss yet with either format- this isn't sports
Weddings aren't sports or birding
More dramatic shots occur with the primes
The answer is in the glass, not the body
They are different animals
Reach and fps - crop. General shooting and deep dof it does fine also
Thanks all for the continued responses. I was thinking of looking at a 40D but it can't micro adjust right? I do agree with all the full frame statements but I have 2 5DII and I want a cropped body.

my 40d works perfectly with my Canon 50 1.4 @ 1.4
the dof is 1.6 times 1.4 on the crop body so it is not as thin as f1.4
depends on what you'll be using on a 40d
if you have third party sigma 1.4 - 50, 85, you might want to get the 50d or 7d depending on how much you want to spend.
if your going to be running canon glass -- f2.8 200 or 70-200 , my bet is the 40d will be fine because again, it is deeper dof, f2.8x1.6 = f4.5. 40d handles this dof fine without MA
I haven't had to adjust or send in 40d even once. Mitch uses his and I use mine and it is good up to iso1250 for closeups during ceremony with the 100L or the 70-200 F2.8 - it is for reach and like having a teleconverter
and it is very good with a tokina 10-17 fisheye which is deep dof
depends on the glass you plan to put on it imo - and you can probably pick a good one up for $400 or less
and 7d will not do better up to 18x12. Mitch and I wll tell you that at low and medium iso's and normal dof 4+ it keeps up with 5dc up to 18x12

But people buy fast lenses for more than DOF... focus speed and exposure would not be f/4.5 on a crop camera. Ever shot a wedding in low light, or sports at night?
Disclaimer: I am not a wedding photographer, sop I don't walk in your shoes. That being said, I do own both a 50D and a 7D, and use them both on a daily basis for sports. Both are great cameras in the 1.6 form factor, but the ergonomics advatage as well as AF, high ISO, & FPS) goes to the 7D.
If you use off camera lighting, the 7D also gives you remote TTL. It also adds micro AF adjust, easier and better AF point selection and back button focus control. If you are going with a crop body, its a no brainer.

Yes, both candlelight weddings and sports
Sports is different, you get the ss up there to ss 1/500 and you stop action and the inverse handheld rule doesn't play much until the times you shoot the coach but usually the coach is animated when you shoot them so you want ss > 1/200. IS can come into play if you are shooting a still coach and move the ss down to get lower iso. IS does no good for high speed action unless you are panning cars or bikers for the dramatic backdrop blur effect.
But the FF comes into play because you can get ss1/50 with your 50mm handheld whereas with crop body and the same lens to be safe you need to up the ss by 1.6 times hand held at these lower shutter speeds to be safe on the handheld rule because of the fov
I shoot the processional with three bodies
The 100L on a 40d at iso 1250 ss1/125 or ss 1/160 with flash to get the long aisle shots
The 50 F1.4 on my 5dc at iso3200 to blast away at 3fps without flash and enough shutter speed
And on a third crop body I have the Toki 10-17 fisheye with flash that I can not only get the final shots before they come to the alter but also as the groom first sees his bride I can get the shot of the groom full body with the pastor
Note the FF played without flash and no flash recycle to worry about on the crop. FPS on the crop are waiting for
flash recycle
Go to DXO mark and study the 50d vs 40 d color sensitivity. Then look at 7d vs 5dc.
For me the hi ISO crossover point is ISO 1600 where I'll move to FF. You can get some good zoomed out shots at high ISO with the cropper, but if zoomed in half body or on the face, if you want sharp eyes and low noise and better colors and tones, the FF wins "consistently" and with less processing.
Canon knows this - ie, the price differential between a shallow dof low noise system and a deep dof higher noise and weaker colors at hi ISO system
That said, crop plays in weddings for reach and close ups up to iso 1250 in the flash less ceremony if you can get ss 1/60 in stable IS or pod scenario at 320 FOV
