Diorshow unlimited or regular??

k so i cannot decide which to get, i have been using the regular diorshow mascara for about a year or so and its incredibule i love it, but a lot of people say that unlimited is better so now i am not sure which to get. and all the make up stores only have the regular diorshow as the one you can try on and sample in the store, so whats your opinion, which is best, o im looking to lengthen,curl and thicken. please dont suggest any other mascaras, i like my diorshow so i will only be buying one of these, thanks so much!
