Revan's command of the force is superior to that of Count Dooku.
In terms of hype, Dooku was considered by Yoda to be his greatest student in an era that is, by feats, the greatest in star wars lore. Darth Tyranus has also been noted as one of the absolute most powerful jedi in the order's 25,000 year history, and an even stronger Lord of the Sith. Revan, at a point far from reaching his peak, was considered the jedi order's most powerful champion, and was considered to be the greatest warrior the republic had ever known. Furthermore, Meetra believed that Revan had a greater command of the force than any she had met, a list that includes the Jedi High Council, Darth Traya, and Darth Nihilus. Note that she would have to be referring to Revan as of the mandalorian wars, as she had never regrouped with Revan since that time. Darth Traya also gave great praise to Revan, believing him to be the ultimate personification of power. When factoring in how immensely powerful Traya herself is with the force, Meetra considering Mandalorian Wars Revan as more powerful than Traya is an excellent accolade, as well as Traya herself seemingly admitting inferiority. In fact, the only beings Traya has shown as much praise for as Revan are the Ancient Dark Lords of the Sith, whose (usually) exaggerated tales of unprecedented feats make them easy targets for such respect. All of these accolades are before his power boost as Revan Reborn, when it is stated he is "far more powerful" than he was at the time of the Mandalorian Wars. Ultimately, whilst Darth Tyranus's accolades are more all-encompassing, Revan gets the edge in terms of hype.
Darth Tyranus was a master of telekinesis, being able to frequently dominate powerful masters of the technique, including Obi Wan Kenobi and Asajj Ventress. Dooku has easily lifted a dozen large stone obelisks, while a rage-enhanced Opress barely lifted 4. Later on, a non-rage ennhanced Opress manipulates a large space shuttle with TK. Dooku has also casually collapsed an enormous bridge, blasted Anakin Skywalker on numerous occasions, and generally obliterated Jedi Council-level beings. Revan was also highly adept with telekinesis, rapidly hurling large asteroids in quick succession while holding multiple asteroids in his grip. During this same instance, he frequently dominates Darth Nox and the Emperor's Wrath with TK, holding them in stasis and throwing them with force pushes. Furthermore, while he was outmatched by the Emperor, Revan was still able to resist being outright ragdolled, and at best the Emperor was able to blast him across the throne room. Considering that Vitiate is the most titanically powerful force user up until his time, that Revan can resist his TK is also a testament to his power. It has also been stated that Revan could collapse a building with TK should the circumstances arise. Whilst both are very potent telekinetics, in terms of feats, Count Dooku has the edge.
The ultimate feat displaying Revan's raw power, however, is his casual handling of Darth Nyriss's lightning. Nyriss's Force Lightning Storm was a power potent enough to instantaneously incinerate very powerful forces such as herself and, according to the novel, Scourge and Meetra. That Revan, who had just woken up from a coma and was most likely still plagued from being drugged, can so easily and so casually reflect such a powerful attack through his "raw power," is a testament to his strength in the force.
Ultimately, their pure feats in overall power output of the force should be very comparable. What should put Revan on top is his solidly superior hype, as he is slightly above Count Dooku in this regard before his power boost as Revan Reborn, a state in which he is recognized by the omniscient narrator as being far more powerful than during his first encounter with Vitiate.
Ehh. I was more or less referring to specific feats/scripted mechanics, rather than a player-determined slaughterfest or a fight we don't know the mechanics of yet.
But yeah, fighting through the Star Forge and taking down uber-amped Malak and what not is decidedly excellent. Doubt Dooku could do it!
