Well, it depends on your personal preference of course. I'll list the sizing for each below:
Style 13836 glam 16 x 12 x 3 drop is 23 cm.
Style 13869 xl spotlight. 12 x 13 x 4 drop is 17 cm for the short handles, the strap is of course crossbody.
My personal opinion? Try them both on. You'll know what works for you when you wear them. I don't like the spotlight because of the drawstring sides, but the glam's double straps are annoying too.
