I have a heavily modified Ender 3 Pro, and have had good and bad times with the buildtac bed (I’ve replaced many times). I’ve tried some PEI beds and had mixed results, but I got this one 2-3 months ago and over ~20 prints it’s been just fantastic.

Amazon link, but not affiliate. Posting because the previous PEI build plate I got was the worst thing ever.
I ended up getting the 410x410 for my Ender 3 a few months ago since I built it out with the Ender Extender kit. I also like it, and the only times I have problems with adhesion is when my filament is wet.
I live in Colorado which is pretty dry, so I don’t have too many problems with wet filament, or at least the problems I have are a much smaller vector than others seem to have. I always try to store my filament in a bag with the drying packet, but I usually don’t even really close it that well. But I’ll also just leave filament on my printer for weeks between uses. I always feel like some of the difficulties I have might go away if I was more fastidious about filament, but I seem to do good enough.
But, I’ve also done all sorts of upgrades to try to get more reliable, without really being good about keeping my filament happy. Upgrades: Sprite hotend, CRTouch, upgraded steppers (went through a bout of really bad layer shift I couldn’t track to anything else, and the steppers fixed it), Klipper, upgraded mobo.
