This question in a sense is a "loaded" question. Of course cone area plays a factor, install plays a huge factor and power plays a factor. I wouldn't even venture a guess on this question unless I had them both in the described setup to compare. Sorry I can't be of more help, it's just one of those questions that has an opionated answer. If budget is a factor, I would go with the ICON combo, it it's not, then go with the XCON combo. They both hit hard. I would say in my opinion that maybe the XCON will hit harder, but again, thats just my opinion and not necessaraly fact.
