I can't say that I ever saw much chemistry between those actors, Definitely nothing on the level as between Trip and T'Pol. When it came to Archer/T'Pol, it always came off as somewhat forced in my view. It also had a somewhat misogynistic feeling to it. Not only because so much of their interaction involved him yelling at her and threatening her, especially early on, but at points it seemed that the writers made T'Pol weaker, physically as well as psychologically. Two instances I can think of off hand are the episode where the human crew members begin to obsess over whatever they were working on as they approach the anomaly of the week and the episode where T'Pol had to hunt down a Vulcan criminal. In the first instance, Archer was able to easily overpower T'Pol physically despite the previously established fact that Vulcans are approximately three times as strong as a human on average. In the second instance, there was a point where Captain Archer literally had to hold T'Pol's hand while she shot the criminal, using the stun setting.
There is also the unfortunate implication that a male and female in a superior/subordinate relationship cannot keep that relationship professional. This implication makes me roll my eyes, because I have seen it so many times. Stargate SG-1 comes to mind, but there are also so many other examples.
To be completely honest, though, I did not find the relationship between Trip and T'Pol to be much better. As with Enterprise itself, there was certainly potential there, but while I liked the idea, I did not find the execution all that desirable.
