Tokyo marui M4s AEG or gas

Hi so im looking at buying an m4 from Tokyo marui that has the strong recoil and less important but still wanted, the open bolt system when ammos empty - either gas or AEG and I just need some facts about the stuff ig ?

For example i really wanna get one that has the good recoil feel (ie gas) however theres AEGs that do that aswell but apparently they vibrate to death or something ? Gas mags are smaller than the aeg ones but they can be shaken to death ?? (Idk if thats correct)

Just any knowledge or experience you guys have when it comes to gas vs electric Rifles with recoil id really appreciate the help
