Why did you choose Sony over Canon?

Full disclosure:

2 weeks ago I posted on r/canon on why Canon over other brands. Although I got some very convincing replies, I can't help that many of the answers were "my dad used canon, so I use canon" or "I have too many canon lens now that I can't escape the ecosystem".

Ok, here's why I posted that:

  • About 3 months ago I was gifted a Canon Rebel T3i (EOS 600D in my country)
  • Realized that I love taking photos so I studied everything I could get my hands on the exposure pyramid, how to operate a dslr camera and photography in general.
  • Wife is very supportive and wants to buy me a Sony 6700 for my birthday (she was doing her own research)
  • Since I am using a Canon camera now, I felt inclined to stick to its "ecosystem" and wanted to convince my wife to get me a Canon r7 instead.

Watching youtube reviews on Canon r7 and Sony 6700 I learned a few things:

  • The r7 has 2 memory card slots while 6700 has just one.
  • r7 produces better colors
  • 6700 has better AF
  • There's very little native lens options for r7 while Sony's third party lens are plenty
  • r7 has better ergonomics, 6700 is smaller/lighter
  • r7 has bigger battery

With all these information I have gathered so far I feel like I'd love to learn more about the 6700 and Sony camera in general from the perspective of Sony users. Granted this is r/sonyalpha subreddit so I expect biases and I'm totally cool with that.

Since having the Rebel T3i I have bought an extra battery and a 50mm STM F/1.8. No other investments so far. The camera was given to me with the EFS 18-55mm kit lens and 55-250mm non STM lens included. I am totally ok moving to a different ecosystem if I need to.

May not be important but adding this info to give more context....

  • I will use the new camera (either r7 or 6700) to continue learning about photography, at least for now. I feel like I am being limited by the Rebel T3i's poor AF functions since it's a very old dslr camera. I feel like I'm ready to go mirrorless.
  • I will be working as an apprentice for someone who runs a photography/wedding video coverage business in another town. Will probably join him in covering weddings once or twice a week. The guy's busy.
  • I love shooting portraits but may eventually transition to taking wedding photoshoots professionally (as hinted above) maybe a year or two from now
  • I live in a small town of 400,000 population here in Southeast Asia where there's not a lot of professional photographers here. Maybe just 2-3 of them and they are always fully booked. So there's an opportunity waiting for me if I keep learning and acquiring the right skills.
