Question second hand juki

Hi everyone, wanted to see if anyone could help me out. I recently bought a Juki DDL8100e off marketplace from a store that refurbished industrial machines (I’m outside USA) but they delivered me an 8300N. Any insight as to the difference and which one is better. Using as my main machine for a wide variety of projects. Mostly curtains and bedding. Having trouble figuring out the difference. Thank you!
