Argos xl vs argos?

Hi all, I’m having trouble choosing between the argos xl and the argos. I want a lifelike packer, so much so that when I am in my boxers in the locker room (I go to gym often) it actually looks like a dick. For this reason, I don’t like packers where the shaft cups over the balls and hangs down. But I want one that doesn’t make me look small as well. I only wear briefs to pack as using tape/pins/harnesses can make me dysphoric however I occasionally use jockmail when wearing regular boxers. My main questions are- does the xl look natural when just packed in briefs or does the head kind of tuck under the balls? would my best bet be the regular? Thanks!
