Neon or cold light? Which one is better?

Hi, have now in my trunk 2 clapping lights Cathodes in it, which shine blue! abe still 2 for footroom ind 4 for the medium console! But wanted to know now, if NEOn is not better? First I got in on cold light, because at work I get one for 6,90 because these are actually for PC mod. NEON, on the other hand, are gruesome expensive at Autotip and for a forbidden thing so much money, didn’t seem to me that way! Well, why I still want to know, it’s because, d As I now grow my underfloor lighting, which is however in neon! HELP. Which of the two light bulbs is best! Thanxxx
