Its mainly going to be affected by your speaker locations and placement. If you do get the new tweeters where do you plan to install them? Or are you willing to experiment with thier placement?
If you have the room, time, and budget go with kick panels. 
Well, if you're familiar with civic coupes (92-95), you know that front speakers are mounted in the door panels all the way on the bottom, while the rear speakers are mounted on the rear deck, on about the ear level. what happens is, the tweeter in the front speakers being on the bottom is not heard as well as the one on the rear speakers, and while the overall quality is great, it appears like the sound if coming from the rear. To my knowledge bass is non direction, and its the tweets that make the difference, so i was thinking about installing a pair of tweets on the side mirror panels, like most luxury cars have, I think it would create a nice balance.
