While I love my cheap amazon textured PEI, ever since I converted to Whambam's PEX FBS I not only don't use the PEI, I also don't use glue anymore. Well a bit for TPU just so it will come off, and the only thing I use PEI for these days is PETG as it will bond to PEX. I usually print in ASA, ABS, and CF for high temp stuff and it handles all of these well.
