Swimbait- which one to buy????

I've been looking at some soft plastic swimbaits and have narrowed it to a few that look good. looking for 4-5" shad pattern:

1. 3:16 Shad 5"

2. Optimum 4" or 6"

3. California Swimbabe Baby E

4. Osprey Talon 4"

Has anyone used any of these? If so, what depth do you fish them at? Most are around 1.5 oz baits, so I assume they'll work down to 15ft and still swim straight.

Thanks
