I have an Ocelot, don't have a Manix, but I do have a Chinook II, which is very similar.
The stretch has an awesome blade and handle shape IMO, but I haven't bought one because it's mostly SS, which I don't like because it's cold, heavy, and scuffs very easily. I also don't care for the Kraton inlay. I'm hoping it comes out with a nicer inlay sooner or later.
The Manix, like the Chinook will be big, thick, heavy, and feel like a tank of a knife in your hand. While the Ocelot is slimmer and smaller, and much prettier with cleaner, flowing lines and the gold accents and paw prints.
The Ocelot will be more comfortable to carry around and play with, and generally EDC.
I like my Chinook more, but I'd recommend the Ocelot to you. It's a more broadly acceptable knife for casual carry and minor tasks.
