I actually get less sides when clen than ECA. I can compare ECA to an all out 4 hours sprint, and clen to a all day jog. I love ECA as a preworkout - It get's me going like a cracked out crazy person. There's no way I could work a job like that. Clen also seems a lot more steady instead of the ups and down I feel with ECA.
I guess at the end of the day it's "to each their own". Both do their job well and it's up to you which you can handle better.
