Don't get Final Cut on Steam! If you have all 3 games (from the Anthology), you probably stil can get Final Cut for free by redeeming here: https://neocoregames.com/redeem/auth.php

Van Helsing I: Utilizes its own unique class.
Van Helsing II: Utilizes its own unique classes.
Van Helsing III: Was released in an unpolished state, utilizes the same framework as Final Cut, is generally considered an inferior option to it.
Van Helsing: Final Cut: Utilizes a rebalanced version of Van Helsing 3's classes, integrates the narrative content of all three games, rebalances gameplay flow, offers an optional high definition texture download. I believe it also has an expanded end-game over the trilogy.

There may still be some benefit to 1 & 2 if you're a completionist (in regards to beating a game with every available class), or are especially interested in the classes unique to the first two games (favoring them over the classes in 3 and Final Cut). Likewise, it's easy to upgrade to Final Cut for free if you own all three original games.

Meanwhile, there doesn't seem to be an especially compelling reason to play Van Helsing 3 over Final Cut at all (especially as it's my understanding that you can import characters directly into Final Cut from any of the three original games). Final Cut does rebalance content, but those rebalances should mostly all be favorable, so the only motivation for playing the earlier games would be based in finding the specific classes of the first two games appealing.

Finally, being that it's twice the cost to buy the Anthology + Deathtrap, compared to Final Cut + Deathtrap [I'm seeing $4 total, for the two of them], there's absolutely no benefit to the Anthology if you're really only intending to play the Final Cut version of the game.
