If you need to support IE 11 you might run into some problems using SVGs:
There seems to be a bug in the IE11 DOMParser. Likely nothing you can do to fix it without a patch from Microsoft.
Other than that I noticed some problems with Safari not rednering SVG dropshadows on the first load. But just fine if your refresh the browser. This wasn’t a showstopper for me so overall SVGs worked great in my latest Project.
