I recently replaced the aluminum bed with a glass bed and so far the results are amazing. I don't even have to put adhesive down as the PLA I am using sticks perfectly. The problem I had was using Creality's slicer software. I switched to Cura and that solved a few issues. The next issue is bed leveling which has been a nightmare. I can get it for a couple of small prints but if it spans over any size at all, it is tough.
