It is much, much more hand-holdable than the version I. I would say heavier than your 100-400L lens, but you could hand-hold if you needed to. You cannot do so with version I. It has great IS, so I'd say you can do it. It is in my opinion the 2nd sharpest lens above 100mm, the first being the 200 f/2L. That is Canon's greatest lens and I would argue the 300 lens is 2nd.
