Not a fan of Sofi (at least for a concert). The acoustics were awful. I have seen the Stones many times and have been to concerts in pretty much every LA venue & I think this was the worst.
For a new stadium --which looks pretty cool from the outside--they were lacking. Very little signage and what they had was small...we had a hard time finding our section and walked almost clear around the place. Almost zero restroom signage unless you were standing right in front of it and even that was tiny. Almost zero elevators...we only saw 2 and they were small (again--very well hidden). I had some minor leg surgery recently and the stairs looked a bit daunting for me.
I had purchased onsite parking ($77!!!) and that was a real cluster when it came time to leave. Concert got out at 11 and at 12:15 we finally started to move....we were sitting in our lot with absolutely no movement all of that time. Other lots on site were moving but not us!
Last but not least---our section smelled like a sewer had backed up. We were all complaining (thank god for masks)--it was vile and no one seemed to know what was going on.
