Is it true, Canon is better than Nikon in macro photographs?

That's actually my opinion based on what I see

Added (1). Dude Jeroen, I told you I see many photos everyday. Canon's looks sharper and nicer
So I here to hear you opinion. That's all dude: D

Congratulations. It's nice to have opinions and share them without a single shred of evidence.

It is true
for point and shoot cameras

All depends on the photographer

No, it's not true. Both companies make fine macro lenses, though Nikon's 60mm macro lens has somewhat of a cult following due to it's excellent quality.

Non-sense. And there's a couple million professional photographers who will disagree with you.

Thats a matter of opinion and the way you photograph and you shouldn't down a persons opinion I personally like Canon better than Nikon and obviously you like Canon better too so your question doesn't seem like a persons opposite opinion will change you mind about Canon being better in macro photographs.

No. Give me a Nikon and a Canon and I'll shoot the same shot. Bet you can't tell which camera shot which picture
