Maybe quoting relevant version numbers would have been helpful here - as is, this topic is wandering dangerously close to starting a religious war akin to 'Mac vs PC'.
Different software products have different strengths/weaknesses, and different versions of each product may turn those strength/weakness comparisons on their head. The term "multimedia" covers such a broad range of totally different end uses, that I believe it's impossible to categorically state:
"X is better than Y." The best we can say is:
"for us X is better than Y in this specific use and in these specific circumstances". I don't believe there is a magic bullet piece of software that is everything to everyone, and I would therefore expect any sensible production facility to keep a few different software programs to hand so they can choose the best one for the task in hand - maybe even Opus AND Mediator among others!
For 'point-and-squirt' multimedia production we switched from Opus 2.xx to Mediator 7 Pro simply because (at the time we switched) M7Pro was more reliable, gave smoother image transitions and much better large frame video handling for the
specific projects we were working on at the time of the switch.
I hope there were enough caveats in there to avoid inflaming Opus-defender passions? I haven't tried Mediator 8 Pro, nor have I tried Opus 04.xx - so my comments mean nothing in the current marketplace for either of these products. We do have upgrade offers for both, but I've given up upgrading just for the sake of it.
