I've had SB, SBSS and now SBTi and they all were different to one another. The SB is a matte finish with a fine even finish, SBSS a lovely high gloss finish and the SBTi a brush metal finish. The SBTi also seems to change in darkness, intensity depending on the light. Seems to reflect the strap colour to a degree. The normal SB seems to take on a blue tinge when in stronger light which the SBTi doesn't.
Personally, I prefer the SBTi and can easily tell the difference and prefer the extra durability of the sapphire crystal screen and DLC of the SBTi. I'll happily pay the extra for that peace of mind and don't care in the slightest if someone else, who I'd most likely never meet, thinks it might be X Y or Z as I pass them in the street.
Just remember, there's no right or wrong way here... just get the one that YOU like the most and don't worry about what I or anyone else thinks because that's all that matters. Don't worry over what others may or may not think!
