JSX vs Templates has almost evolved into a holy war at this point within the js community. There are benefits and drawbacks to both, so you'll find people coming down on either side of the argument.

My main reason for preferring templates over jsx is that it allows to separate the functional component code behind the scenes from the actual rendered html in a cleaner fashion, imo, than just embedding the html directly into the JS code. I could also say that, due to my background, I am just more comfortable with it, as well.
