The Tracker is my favorite ever Webley rifle. As my sig suggests I'm currently on the look out for bits to rebuild a couple of them that I own which are in a sorry state. Apart from looks and compactness they don't have much else going for them, but there's just something about the Tracker which I love
As this thread is about the best Webley my vote also went for the Omega. If you want a good first impression of a Webley then the Omega is a better bet than a Tracker! Bear in mind that they are an old rifle now and finding one which hasn't been tampered with will be a challenge.
The Tomahawk and Longbow are right up there too no doubt. Technically they are better than the Omega. However, I believe the Omega was a better rifle of its time than the Tomahawk and Longbow were of theirs.
Cheers
