Which one is better

Hi

I am making new platformer game for backgrounds i have possible two solutions.I prepared two generic script. Both seems fine as graphical quality
1- 512x512 PNG and UV tilemapper (Basically builds A plane which has custom UV coordinates decided in edit mode which has approximately 80 vertex)
2- Generic Math to Plane Maker (I gave that name
It generates two lines from math equations then builds mesh between them again in edit mode which gives approximately 400 vertex but no texture needed)

Dillemma here : Which one is faster. math plane maker usage seems better also it has unlimited zoom capability.BTW my second question will be which one seems better but i will send SS's when i got home


Thank you in advance...

Side Note: when i finish project i will send both script. They will be very useful for 2d games.

 

I am simplifying my question :
Which one is more efficient in terms of speed :
80 veritices with 512x512 texture
400-500 veritices with no texture
