tldavis357, I use the Brother embroidery threads or Isacord or Creek Creations Brother threads for embroidery in my Brother 780D. & Madeira for the variegated threads.
Emb machines are like ovens in that each is the same yet different.
Watch for thread tangling as the thread comes off the reel. Thread wrapped around the spool can break a needle. Not fun to try to fix up.

I am sorry I do not know about your machine. I would suggest to purchase only a small amount from different companies and see which one your machine is happy with.
If I have not said welcome to you yet I am saying it now. I hope you like our family here.
Angie
