This year I switched from Nikon to Canon and have done over 20 weddings on the Canon system. I have two 5D3's and four 600-ex-rt's. I am finding the auto color balance of both systems to be about the same. I shoot most of the day in auto color, then when I get to the reception and put the gels on I find I have to manually set the color to get anywhere close. I normally choose something between 2600 and 3000 for color temp.
I started with the Canon orange filters and had good results but had minor problems with removing the gel holders from my belt with the Canon filers in them. The filters would slip out of the gel holder when I was handling them (think fast moving wedding photographer with four gels to install quickly). I ended up buying a couple of large sheets of filter material from amazon. I cut out filter pieces that were a little smaller than the Canon ones and taped them into the gel holders. With the smaller ones tapped in I no longer have issues with the filter slipping out of the gel when I am retrieving or putting the filers away on my belt. My cut out filters are a bit shorter than the canon and do not reach up to the sensor and clip area of the gel holder so the camera can't read the color of the filters but with manual settings of the color balance the results are the same. I shoot raw, so I just want the color close enough to get good exposures. I adjust the final color later in post.
I only ever use just one filter color so I don't need to change filters.
