Both players are in scintillating form and don't look like stopping any time soon. Suarez grabbed himself five goals in the past week while Aguero got two, pushing the Uruguayan ahead of his South American rival.
Suarez missed the first five games of the season and has now scored 14 goals in 10 matches. Only two other players in world football can match that type of goal ratio.
Aguero has missed just one match this season and has 12 goals in 14 appearances. An impressive tally, but he has fallen into the shadow of Liverpool's number seven.
The Argentine's chance conversion is not as good as Suarez's either. The Uruguayan has scored 27.5% of his league chances while Aguero has scored 24% of his. That's not a huge margin but it still pushes Suarez out in front.
Suarez has become a lethal finisher of chances since his arrival in England. He struggled in the first 18 months to score regularly but he is now one of the most feared goalscorers in the world. He has scored 14 goals from just 31 shots on target, an average of a goal every 2.2 shots on target.
Aguero has been a constant goal threat since his expensive arrival from Atletico Madrid. He challenged for the Golden Boot in his first season but struggled under Roberto Mancini last season. He is now in the form of his life, though, scoring a goal every 2.5 shots on target.
Unsurprisingly, both players' shooting accuracy is the best out of the forwards at their respective clubs. Aguero has hit 60% of his shots on target and Suarez has a similar figure, hitting the target with 61% of his shots.
As you can see, both players are close together, but Suarez is edging Aguero in all areas. Goals scored, shot accuracy and shot conversion have all been dominated by the Uruguayan. Chance creation is also another victory for Suarez.
Aguero and Suarez are different types of players. Suarez is a more creative, all-round forward whereas Aguero - while he tries to create as much as possible - is much more of a poacher than Suarez.
The Manchester City front man has completed 23 key passes this season, assisting four goals. Suarez, on the other hand, has completed four more key passes but has two fewer assists. This means that while Suarez is creating more chances, his team-mates aren't as good at scoring as Aguero's, or perhaps the chances that Suarez creates aren't as good as Aguero's. I'd pin it on the former.
In terms of Squawka Performance Score ranking, both players come second at their respective clubs. Yaya Toure has pipped Aguero at City while Steven Gerrard leads the way at Liverpool. Suarez is way ahead of Aguero, though. The Uruguayan has scored 607 points compared to Aguero's 551.
Only Aaron Ramsey and Gerrard have scored more points than Suarez this season.
You could pin this down to Suarez's all-action game and that he is, without doubt, Liverpool's most important player. Aguero, on the other hand, isn't as rounded as Suarez and arguably isn't City's most important player.
Suarez's importance to Liverpool can be proven with his unbelievable performance against Norwich City last week. It was up there with one of the best matches a player has had in the Premier League. With the Reds missing Daniel Sturridge for the next month, Brendan Rodgers warned his players not to rely on Suarez to score all of the team's goals.
Suarez had other ideas, though, scoring four goals - three of them incredible - and assisted Liverpool's other goal on the night. He scored 193 points in the Performance Score system to notch the highest score this season for a single player from Europe's top five leagues.
In that match, he hit just one of his seven shots off target. Two of his goals were absolutely stunning and will surely feature in the goal of the season polls in May.
We all know how confident Suarez is when taking players on and it's seen in his statistics. He has completed 40% of his take ons (33/82) compared to Aguero's 38% (23/60). He is actually averaging 8.2 per game. This confidence and exuberance is what sets Suarez apart.
Suarez has done wonderful things with a football this season. Aguero has been fantastic, too, and will no doubt continue his superb scoring form. However, he just can't get near to Suarez's level of performances and the figures that he's posting. He has been absolutely devastating and, if he carries on like this, Liverpool will be pushing the top four all season and may even have an eye on the title.
You could argue that, as an out-and-out striker, Aguero would pip Suarez but as an all-round player who can create chances, beat men and score incredible goals at a ridiculous rate, the Argentine comes nowhere near close to Liverpool's Uruguayan superstar.
