I prefer MTT's vs cash games because of return vs. investment. This may be due to my style. If you checked my stats you'd see that I cash 16% of my tourneys and 77% of those cashes are final tables from big fields (average 626 entrants). So my hyper aggro style of play is much more beneficial in MTT's because I either get knocked out early or I make the final table (with the occasional late no cash run when variance kicks me in the teeth). When playing cash I have to risk larger to win moderate. When playing MTT's I can win 10 - 200 buy ins for the cost of a single buy in, and do this over 12% of the time while not investing much time in my losses.
