It sounds a lot creepier than it is. Plus with solo as I recall you have to do several static line jumps at low altitude before you get to freefall.
With tandem, I got an 8000 foot freefall
It’s not the creepy factor (though there’s that, too) so much as who’s in charge of my life. What if the guy’s having a really bad day and decides he’s just not going to pull that ripcord? At least with the solo method you can check the equipment and operate it yourself.
