For a long time Nikon and Canon user have been at war with one another, why?

I use a Canon, the other day i was on a photo walk, it was very interesting to see, all the Nikon users stuck together as one as well as Canon users, and there were disagreements on what camera is better than the other, why is this such a big deal, if you ask me i dont care what you use as long as you know how to use it!

Amateur photography learning the ropes?

I'm trying to teach myself how to take full advantage if my nikon d3000 via the Internet.It's all very overwhelming, but I think the best way for me to get a grasp of aperture, shutter speed, and iso is to know approximately where these setting should be at in different scenarios and then make adjustments from there. For example lets say I'm taking photos of my daughter outside on an overcast day or in the shade with a blurry background. Where would be a good starting point? And how about the same situation indoors near a window? Or outside on a sunny day? If you have any other helpful tips for me I would really appreciate it. Thank you so much!

Best flash photography setup?

I am buying a new flash setup for a photography trip in the French Alps. I have a Nikon D5000 (max sync speed 1/200s).
I have two different setups:
1:
Yongnuo YN460ii x3
RF-602 x3

2:
Godox EX400 x1
Yongnuo YN460ii x1

I was wondering which setup would be best for freezing fast action, skiing and snowboarding. Also it would be used for portraits.
Which setup do you think would be best for my needs?

Thanks
