This one has a more mysterious tone in comparison to the first Out Of Time CD, with the Fifth and Tenth Doctors teaming up to investigate the Cybermen's invasion of French history. There's not as much bickering as between the Fourth and Tenth Doctors but I don't mind that so much, because we got plenty of that with Time Crash.

What Gates of Hell offers is something new and different from Time Crash, with the Doctors operating more as sort of time investigators rather than bantering about forgetting to put the TARDIS shields on.

It does a good job with the Cybermen, using their stealth abilities remarkably well, and showing the way that they manipulate a human host to achieve their means (as they have done before with Tobias Vaughn and John Lumic).
