Here's what I have tried so far, and what I thought of them:

1.  The new Prusa textured PEI build plate.  Excellent!  Works just as advertised: sticks when heated and releases (often automatically) when cooled afterward.

2.  The original Prusa smooth PEI build plate.  Not so good.  PETG sticks too well to it unless a release agent is first applied.  It's difficult to always apply just the right amount of release agent (neither too much nor too little), and some release agents have to be cleaned off the printed parts afterward, which is extra work I'd rather not have.

3.  BuildTak.  Even worse than the smooth PEI build plate.  Without a pre-applied release agent, PETG practically welds itself to the build surface.

4.  GeckoTek.  So far, so good.  Seems to work as advertised.  Similar useage to the Prusa textured build plate described above.

 

Anything else that's especially good?

I've become a big fan of the BCZAMD steel sheet. Using it on both MK3S and Mini. I've been printing on it for months now, holding up very well. The pattern is coarser than the Prusa sheet but I've come to really like it.

Great!  Thanks to your recommendation, I just now placed an order for one.

 

Anyone else have any favorites?

I see in your comments that you are not a fan of the Prusa smooth PEI sheets, but I have no issues with them.  If avoiding the use of any type of release agent is your goal, then the Prusa smooth PEI probably isn't the choice for you.

For me, quick wipe of the PEI sheet with Windex (generic brand really) using a paper towel is pretty much painless.  I print almost exclusively in PETG, 10 -15 prints per week.  I've never had a print lose adhesion prematurely nor have I had any problems getting them off the sheet after it cools off.

I have been using Thekiinngg on a few of my MK3S='s and a mini and the textured sheet gives great adhesion, and instant release.   I am liking them alot, will buy more.

all of my Prusa sheets smooth and textured have been great for PETG no issues, I do want to try one of the satin sheets but none available at the time of writing this, no big deal though it can wait.

Same here, and ditto on the want to try the satin plate.

I also have no problem printing various materials with the smooth and textured Prusa sheets. I have also tested the satin sheet and it works just as well. I like the texture even more than the normal textured one because it is a bit more subtle.

Anyone tried PEX?  It's one of the print surfaces now being offered by WAM BAM. Is it same PEX material as is used in plumbing water supply lines?
