Are 3.73 gears worth it

When I bought my 98 GT, it already had 3.73's (otherwise stock) in it, so I couldn't really compare it to stock at first.

Then I drove a friend's 98 GT with stock gears, and after that, it felt like his had quite a bit less get-up-and-go. Seemed like his was in need of a bad tune without the gears, either that or it seemed like I had more mods than him. Gears are a really good mod, if you're talking bang for the buck. You can really feel the "seat of the pants" difference after you put them in.
