Question about Ligers?

I had seen a comment on a video I had watched stating a Liger would easily overwhelm a Lion or a Tiger in a fight due to it's mive size. I thought, however, I had read an article quite a while back and that said a Ligers size is actually a detriment in a fight because it wouldn't be as fast or as aggressive (Because Male Ligers are sterile they have low testosterone and therefore are more docile) than the Lion or Tiger. Does anyone have any knowledge or ideas on the probable outcome?? Just curious. Thanks :-)
