Bro, don't worry so much; Most important is you to choose what you feel best and which you prefer more; People who prefer different system will favor the system over the other. Some people prefer the feel of Canon, or maybe the "brand/name" like fashion, the design and menu system, the performance, etc. or vice versa. Most important is what YOU feel, not others. The best is to try out yourself.

As for pictures, it's more about skills; Camera is just the tool to help to take picture, just like art tools help artist paints. Of course, good tools will help, but skills is still more important.
For the colour differences, if there are differences, probably becuase they shoot JPEG, but EVEN within same system, the JPEG image colour produce from different model of the SAME brand can be different.

ANYWAY, eventually or most probably you're going to edit or post process (pp) the photos (especially if you shoot raw), so you're still going to tune the colours to your personal preferences. Even if you're not going to pp the photos, there is still "picture control" in the camera you can set AND also adjust to your personal preferences;
So, first, check with the person who tells you about the colour thingy, do they play and adjust the "picture control" or do they do pp?
Personally, I would say this is not really an issue unless one just use standard/same picture control and compare.

1)Wider sensor means better ISO handling capability (you don't have to bump up your ISO as much as APS-C do, as your sensor capture more light), you get the actual focal length of your lens mean when you buy 50mm lens you will get 50mm lens unlike ASP-C with it's cropped factor (Nikon 1.5x, Canon 1.6x, Canon APS-H 1.3x), built quality indeed, usually come with better specs like 8/9 fps, superb AF system, CLS capability, better control in the body (not like entry level body where you have dig up the menu to change the control), of course better control placement.
2)he is correct I myself do recommended starter to get either D7k or D3100. APS-C sensor model doesn't make any much difference, except the CLS, built-quality and AF.
but entry level AF is actually sufficient <- come back to the person.
Lens is the major things when we are talking about ASP-C even FF lens still do a major difference I suppose. Do remember model does deprecate, today you say d7k GODLIKE 2 years later you say so-so. so does lens do deprecate, however good lens does deprecate slower true fact, 50mm 1.2 Ais <- still owning in its class, however due to technological problem there is no AF on the lens.
3)I got to say I am more than agree, PP is boring, tiring and taking a long time.
yet if you don't do it <- usually I am too lazy to do it.
You wouldn't get amazing (woah2) color tone <- Correct me if I am wrong on this

Get whatever thing you feel you suit most, it doesn't have to be Nikon, or Canon. Leica also geng larr   
LOL...
you are more than welcome.
I can't hold my patient when PP it on my laptop. even open RAW file also hard. 
CPU processor goes to 100% immediately 
RAW PP 
I takes me more than 3 days for 50 pics I guess
Will do better bro. 
Thanks. I really2 need to learn on that.

When lighting is just nice, need to apply a bit SKII only .

2) Don't worry, there're no rules for photography nor must to do PP.

Most important is whether you're satisfied with the results. OR if you're shooting for somebody/client, just make sure they like it; If they like move vivid colours, then adjust the camera picture controls, etc.

PP is just like "add-on"; You can explore later when you want to. Who knows, maybe one day you see some photo looks really nice after PP, then you have the sudden urge to do it; just like how you were "awaken" back into photography

DSC_3103 by lpy_87, on Flickr

mean PP to get higher contrast? this is no edit...

I never realized I've posted it. xD
edited. change the perspective of the plane.

is this considered cat-eye bokeh? 

cat-eye bokeh.
round round punya bokeh. like cat eye.
I myself not sure, therefore still ask. hahaha

nop. different color tone bro the one I posted initially cold color tone..
just some perspective. kindly check it. haha..
Will do gallery thread later. Thanks for the suggestion

In terms of IQ, the Nikon 1635 tapao the Canon leh lol.

You happen to know Nikon UWA are excellent.

produk gagal lol

Keep ur 18-105mm.
add an ultra wide or a 50mm prime.
how often u'll need to zoom more than 105mm for walkabout n travel.??
i guess u'll cry for wider zoom more than super telezoom for a walkabout or travel.

just my 2 cent

i also donno. but if i compare primes and zoom, primes will be brighter...
