It really depends on WHAT you are interested in photographing.

Fully agree with first statement, but I feel it conflicts with the second. Yeah, Canon and Nikon are best at what YOU do (sports with big, fast SLRs and lenses where high performance, motion tracking autofocus is king), but not necessarily what the OP wants to do (they haven't told us yet).
For instance, if OP wants to go hiking or backpacking in their beautiful surroundings and take landscape photos, maybe a super small and light micro four thirds camera from Olympus, like the OM-D EM-10 (http://www.dpreview.com/products/olympus/slrs/oly_em10), would be a lot better than a DSLR. These little cameras still offer the same level of full manual controls and customization as with a serious DSLR (and more of these things than comparably priced entry level DSLRs, like a Nikon D3300 or Canon 1200D). M43 also has a wealth of lenses to choose from much like Canon and Nikon, with plenty of quality zooms and primes.
Really I think the only reason to go dSLR these days is if you need high performance autofocus for tracking fast moving subjects. Optical viewfinders are certainly nice to use, but newer electronic viewfinders are really pretty good, and of course have their own advantages. With an eVF you can see how the image will look in real time, before you snap the picture. So if you're shooting in manual mode and have chosen to bright of an exposure setting, the image will look overly bright in the eVF. I could see this being helpful for a beginner, but it's useful for anyone really.
Smaller sensor systems like micro four thirds, and to a lesser extent APS-C, do sacrifice depth of field isolation compared to full frame cameras. OP, this is the ability to have sharp focus on say a person's face but have the background totally blurred out. Larger sensors give you a greater ability to do this, so if taking portraits is important OP should try to go at least for APS-C if not full frame. Smaller sensors will tend to have more depth of the scene in focus, which can be beneficial for landscapes where generally you want everything to be sharp.
But even if you want to go full frame or APS-C, which is traditionally the realm of DSLRs, there are now many APS-C mirrorless options (Sony alpha series and Fujifilm being the two best systems) and Sony is even introducing full frame mirrorless options now (A7 series).
I do agree that going to a camera store and seeing how you like the feel of different size and style of cameras is important. Not nearly as good, but much easier, is this web site that lets you compare the sizes of cameras (with lenses too) side by side:
http://j.mp/XDm6LfI put in a range of current interchangeable lens cameras, from a tiny M43 option from Panasonic that is the size of a little point and shoot and will fit in your pocket (if you don't have a big lens on it), all the way up to the big full frame Nikon D610 (and they have even bigger ones than that, if you want a tank for a camera).
