2018silverado4x4

So I have a 2018 4x4 with the 4.3 and oem 20s. They feel great on road but are absolute crap off-road and have gotten me stuck a few times just in loose dirt. My stock tires are about at the end of their life so I’m looking to throw on some duratracs or at3s. Basically my question is, for those with factory 20s that went with ats was it worth it? Because I’m seriously considering swapping my 20s for 17s. If I go 20s it would be 285/60r20 with level and 17s I would be going 285/70r17. Anyone who is still rocking the 20a and is happy? I really just want extra the traction.
