I wouldn’t call myself an experienced user, but the one thing I wish I had known up-front is to get the gold PEI plate and the liquid glue (with the caveat that I don’t print much PLA). It’s all I use: I’m careful not to touch the plate with my fingers (fingerprint oils) and smear a small amount of glue over the footprints left by the previous print. It’s so easy and has worked great for me.
