Janet: So - Canon or Nikon? My camera broke and I'm in a desperate need of a new one
Gina: Team Nikon here. I had a Canon once, but after buy a Nikon I'd never use Canon again
Janet: Ok, why's that? I liked it myself
Gina: It was all right, but I think with Nikon you get better colours, more vivid, and better focus
Charles: Hm, I'd say Canon all the way. You get more options to adjust your settings and in the end you get better results. You do get different photos from those two brands, but I prefer photos taken with a Canon, they're softer, in my opinion
Daniel: What were you using before?
Janet: Pentax and Canon, but a long long time ago
Daniel: I think you should compare photos taken by each camera and then decide, Nikon and Canon are really similar, they're both really good brands
Janet: Thanks everyone!
Daniel:   here you have a link to some articles with comparisons

Briefly summarize that dialogue.
Janet's camera is broken. She's undecided whether to buy Canon or Nikon. She used Pentax and Canon before. Gina uses Nikon. Charles advises her to buy Canon. Daniel sent a link to the comparisons between cameras.
