Yes, it's unfortunate but true that despite SVG being a true standardized format, there are few applications that are 100% compliant. Even Inkscape is not 100% compliant, although it is definitely our goal to become so one day.
As a general rule, Inkscape's SVG is closer to compliance than many other (even commercial) applications, so many times the issues are due to issues with the other program. If you get really curious about the incompatibilities, a good judge is the program Batik. It's probably the most compliant program out there, so if there is a difference between Inkscape and Batik, we generally assume Batik is correct.
Of course, all this is neither here nor there for users, who just want the programs to interoperate...
After all, Inkscape itself differentiates between Inkscape SVG and "plain" SVG. If there is no difference, why the output option?
I think a good way to think about Inkscape SVG and "plain" SVG is like between a color photo and a black and white photo. The B&W photo will display correctly on a printer, its file size will be smaller, and you may have fewer issues using it in various graphics programs. But despite all these benefits, it doesn't have color!
Similarly, "plain" SVG will display correctly in more programs, be smaller in size, and have fewer issues, but it's still "less" than the original Inkscape SVG.
I think a better comparison would be between a PSD of an image and a JPG or PNG. THey'll both look the same when you load em in photoshop (assuming you used decent compression settings), but as soon as ou try to edit the jpg you'll find you've lost all the usefull stuff like layer info. That being said, theres a lot more places you can use a jpg than a psd, if your loading it inot word or whatever the psd wont work. Both inkscape and plain SVGs should render identically if the viewer can cope with the file, (its not visually "less" which is why i dont like the b/w analogy, the less is purely an editability/compatability thing) Saving as plain does increase the places it will render at all tho.
