Features and MySQL performance

I have one question regarding MySQL performance and features.

Features with approx 15 repeating variations.

I have 2 options

A. features like simple (others)text, manually added variant by each product

B: features like selectbox-text, there is a variant selected by each product from offer.

There is a table cscart_product_features_values filled with same text in option A. With option B there is only variant.

Is there a difference between these 2 options which can effect speed and power of page?
