Actually, the tyrant is smaller, and has fewer options than the Carnifex. It still is nastier though.
The most dangerous tyrant build in my mind for 4th edition would be the dakka flyrant. Pumping out 12 reroll-to-hit-and-wound shots right before assaulting with a higher initiative than you is enough to wipe out most squads.
The best way to combat a tyrant is shooting it with AP2 weapons. It has difficult if any invulnerable saves (6+? please...).
The difficult part is catching it out in the open. A flying tyrant's mobility is its deadliest weapon. It can lurk behind aread terrain and wait for a chance to strike.
Squad support is very important as you're unlikely to have one squad that can absorb its charge, especially if its tricky and limits its kill zone on the charge. Have a counter charge squad ready and keep those hidden powerfists handy.
The tyrant is going to take a hit in 5th edition though as true line of sight, counter charge moves and running (which makes the walking, 3 guard tyrant look more attractive) take effect.
