The most successful in terms of outcome? Short and medium term, clearly no. Long term? TBD.
If the goal was to kill Israelis, torture and humiliate them then yes it was a tremendous success.
Obviously their approach can't be seen as any form of success for the people of Gaza themselves who have now gone from chronic despair to acute despair. I don't believe that anyone could characterise how this has played out as a success for them.
Lastly, from a geopolitical perspective, even for Iran this can't be viewed as a win in the short term. Hamas' cold-blooded disregard for lives on both sides (and they _had_ to have know what the Israeli response was likely to be), means Iran can't be as overt and full-voiced in their support of Hamas (vs supporting 'the people of Gaza' or the Palestinian cause more generally).
Like I said, there's not enough info to be able to tell what the long-term implications will be yet, but in the short term this has been an unmitigated disaster. In my opinion.
