Gillette have a pretty large catalogue and your list is certainly not exhaustive, but since your aim is to not waste money I'll drop my thoughts in ... which largely echo above. I'm not a massive fan, generally, of the Russian made blades and have an erring towards the Indian blades as my preference. I also have a personal preference for plain stainless over platinum.
Gillette PermaSharp (Russia) - a 9/10 for me, very sharp, yet comfortable and consistent
Gillette 7 O'Clock Sharp Edge (Yellow/Russia) - 9/10 again, super-sharp (probably the sharpest from the Russian plant)
Gillette 7 O'Clock Super Platinum (Black/India) - 8.5/10 super-smooth and good lifespan (probably the best from the Indian plant)
Gillette Winner Special Platinum (India) - 9/10 not as smooth as the Gillette 7 O'Clock Super Platinum but definitely a "Winner"
Gillette London Bridge (Shanghai) - 8/10 seethingly sharp, almost vampiric! Probably Gillette's sharpest?
Gillette Super Blue (Shanghai) - 10/10 almost perfect balance of sharpness, smoothness, comfort and consistency
