luckyrawatlucky - If you want to export to Android v4.0(Android Ice Cream Sandwich) and above I suggest you use crosswalk since it is faster but if you plan to export to Android v5.0 and above then use Webview since it is faster and also smaller apk size. I don't think there are any connections with effects and your type of export I am aware of but since you are exporting to mobile, I suggest lessen the shader effects or not use them at all if possible.
Also, If you plan to export to IOS then use the Webview option.
