Hullo again…
I was just wondering…is there a difference between Env Maps and Ray Mirror?

yes
ray mirror is difficult to blur
doesnt support halos and light flares [halos]
ray mirrors are easy to get accurate relections from [envmaps are usually an approximation]
they reflect everything [envmaps dont’ have to]
… umm, I guess that is about it
envmap is good for animating reflections they render quicker. Raymir gives a nicer effect put is cpu and memory heavy
so if i were to make a chrome sphere, then it wouldnt matter whether i used a EnvMap or RayMirror…
?

envmap is less detailed ray mir gives a clearer reflection. envmap is a simulated reflection that is blurry
That’s partly true. Envmap have a resolution parameter, so you can have them as clear as you need.

envmaps have 2 main problems:
on the other hand envmaps are way faster… making them good for animation, and as you pointed they can be blured to creat a glossy effect.
