I like the new ones better and the old style was my main knife for 8 or 9 years. I loved them and the old Spyderco Enduras, but the new Voyagers are better in my opinion and superb bang for buck. For me design and build quality is most important as long as materials are good enough and the new Voyagers are close to perfect for a working/back-up defense folder.
The handle is great with locking into the hand using multiple grips and the thickness is great to work with (thin is better in pocket but thick is better out of pocket). Stark contrast with open-construction, thin liner-locks and frame-locks that are not very good beyond carrying in dress slacks, fondling, or light cutting tasks a few times a day.
The blades are very attractive and FFG Vaqueros I have experience with are real cutting machines. Fit and finish is better than the older versions and as good as any folders I've had but might be luck...
Getting another one soon, probably Large Tanto.
edit to add - For me they are great opening and closing also, quick and secure to open and close with one hand. Can do inertia opening but not as easy as old Voyagers that would just fly out - you could hold an old Voyager in your hand and smack your forearm with your empty hand and get the blade to deploy and lock-up. The new ones are smooth enough that a nice push with the thumb will deploy and lock the blade and to close it you just let the blade tang drop on your index finger when you press the lockbar release, then move it out the way and close the blade with your thumb on the thumb-stud.
