Third is hardest to read. First looks nicest, but the second one is okay too. If you must.
Trouble with the first one is that it's a bit lifeless, but the second and especially third don't add anything exciting but look more blurry. Instead of blurring, could you possibly use a particle? Or a shorth flash or blink? Or any effect that temporarily adds life but keeps it clean and readable.
I'd prefer that, but that's just me.
