Neither.
On a crop-sensor body like the 7D you'd be better off getting the Canon EF 28mm f1.8 USM for 2 reasons:

I agree. Crop sensor + 50mm is just too much.. A 28mm or a 35mm would be a much better choice.

That being said, on a fully frame, I have the Sigma 1.4 50mm for my 5DIII, and I quite like it.
Standard 77mm filter size I can share with my 70-200 II and my 24-105.
It needed MFA of 19 before I sent it and my 5d III to Sigma. Got it back and it needed MFA of 7.

i have the canon 50mm f1.4 on 5d markii.. from my experience this lens is not very sharp, especially on wide open f1.4. it cannot be compared to other L prime. however, if u slow down to f1.8 or f2, the result are very sharp.

And actually sharper than the 50L above f/2.8.  I'm serious.

Is this a common issue with the Sigma 50mm 1.4? I have one on my 5D3 on +20 and I reckon still needs +2 more to be acceptable.

The 50mm F 1.4 is terrific: Beautiful saturation, fast and sharp as the night is long. I get great photos at 1.4 and beyond and don't know what the negative rap is about.

I pained over this decision as well.....I definitely wanted autofocus..and I found the "range" of Canon's offerings to be quite bizarre.  I just didn't see why they did not have a screamingly great, with pro-build quality,  moderately-upper price range,  50mm lens for their full-frame cameras. How many years have they had to get this right???
Let me also say...I am NOT a Sigma fan in any way, shape or form....but I did a LOT of reading and researching about the Sigma 50mm f/1.4 (with all the extra letters after the name???)...anyway...according to my research this was going to be my selection....purchased from a reliable retailer with a 30-day return policy so that if I got a bad copy with any of the focusing issues (that I am sure that you are aware of), I could return it no questions asked. 
Have to say...this lens is GREAT. The price is right for what it is. It is sharp as a tack slightly off wide open, focuses lightningly fast and has incredible bokeh.  This will, without a doubt, be the only Sigma lens I will ever own...I personally think that they nailed this better than Canon. Just my take on it. I have been shooting for over 40years and when I pick up this lens I have a very positive feeling when I go out to shoot with it. It helps me create great images.
Take the leap!  LOL! Just my two cents.

Yup - very common... They told me they did a 'firmware upgrade' to fix it...

it's not unusual for any sigma lens. I've got a 24-60 2.8 that's perfect at 3 metres with +17, +15 at 2.5m and +10 at 2m. Also, all the calibrations are different across the zoom range AND the focal plane changes when you stop down. It's an incredible lens, it's so bad in so many ways that it's a complete statistical anomaly.

Some data wouldn't hurt the conversation. 

50mm prime lenses:
Canon 1.4:   http://www.photozone.de/canon_eos_ff/564-canon50f14ff?start=1
Canon 1.2L: http://www.photozone.de/canon_eos_ff/472-canon_50_12_5d?start=1
Sigma 1.4:    http://www.photozone.de/canon-eos/522-sigma50f14eosff?start=1

Be advised that these tests are all on FF bodies.  There is a website section for crop bodies, but the only data they have on these three lenses is with an 8 MP sensor (an old 350D).  I've omitted that.

I'm not saying that hard data is the only thing to rate IQ with.  User experience is vital, of course.  I defer to the forum for that.

But the data says that once you hit F/2, there really isn't a compelling sharpness argument to use the 1.2L over the 1.4, so I bought the 1.4.  No alarms and no surprises.  It's up with the 85 F/1.8 as one of the highest [performance divided by cost] lenses you can buy, IMHO.

Advise against the Canon 50 F/1.8 as it is a super duper cheap build, and it's also slow & loud at focusing. 

I firmly agree with those folks calling for the 28mm or 35mm lens instead if your intentions are a single lens for walkaround.  On your crop, a 50mm will be a portrait length and not a walkaround length.

+1.
However, I think my 50 makes a great portrait lens on a crop, so I like it. but it's useless for a walk around

Thanks for all the comments and advices guys!!

I think I'm leaning towards the Sigma now. But I really want the f/1.2 50L too!! just not sure if its the right investment right now since its my first 50mm and first "aftermarket" lens.

The reason I choose the 50mm focal length as my first lens is because I like shooting street photography and I shoot quite a bit at that focal length.

If you're going Canon, you'll be much, much less disappointed with the 1.4 lens.  I NEVER miss with the 1.4, but the 1.2L is just too hit and miss.  I don't know why, but it is.

Still can't decide which one to choose!! Lol

I wus reading about the Canon 50mm f/1.4 somewhere last night and some people were saying that the Canon has a tighter field of view than the Sigma? Is it because it has a smaller glass or it's not an exact 50mm?
