My wife's tradition for Christmas breakfast is Eggs Benedict, so gotta poach them eggs. We got some of those silicone egg poaching cups from some store or other a long time ago and they work great. The eggs do come out a little dome shapped but I'm fine with that, you don't lose any egg to the water like can happen with traditional poaching from just cracking the egg into the hot water.

The issue wasn’t the eggs themselves sticking, it was all the whispy pieces of egg white that floated around and finally settled on the bottom.
It’s a shame sous vide can’t make a good poached egg equivalent otherwise that’d be the solution.
