I know we have 2 lenses (one for indoor and one for outdoor that has a larger zoom), and the whole getup cost almost 2k about 4-5 years ago.
If you don't mind educating me, how can I tell the difference between the 2 when they have the same zoom?

I'm a little confused by your terminology. You say that you have 2 different lenses, but have the same zoom. Are you saying that the lenses have an over lap in focal lengths and you are using a common focal length for your comparisons. For example, lets take all of these zooms into consideration:
AF-S DX NIKKOR 16-85mm f/3.5-5.6G ED VR
AF-S DX Zoom-NIKKOR 17-55mm f/2.8G IF-ED
AF-S DX NIKKOR 18-55mm f/3.5-5.6G VR
AF-S DX Zoom-NIKKOR 18-55mm f/3.5-5.6G ED II
AF-S DX Zoom-NIKKOR 18-70mm f/3.5-4.5G IF-ED
AF-S DX NIKKOR 18-105mm f/3.5-5.6G ED VR
AF-S DX NIKKOR 18-200mm f/3.5-5.6G ED VR II
AF-S DX VR Zoom-NIKKOR 18-200mm f/3.5-5.6G IF-ED
AF-S NIKKOR 24-70mm f/2.8G ED
AF Zoom-NIKKOR 24-85mm f/2.8-4D IF
AF-S VR Zoom-NIKKOR 24-120mm f/3.5-5.6G IF-ED
All of the above lenses have a common zoom range of 24-55mm. Lets pick a focal length in that range, 40mm. Do you think that all of the above lenses at that focal length have the same minimum focal distance? I suspect that the minimum focal distance at that focal length (40mm) will determine the maximum magnification (for macro purposes) you will be able to achieve. Do you think they will all be equally sharp at a given magnification and focal length? Do you think the distortion will be equally corrected in all of them in that condition? I suspect that there might be more design trade-offs in say the 18-200mm lens which has a very large zoom range versus say some thing with a more limited zoom range like the 24-70mm (which is more than double the cost of the first zoom).
