Favorite Print Tuning Models - is Benchy Still King?

[Demosth]

I wanted to reach out to the community and find out what you use as your go to test print / calibrate prints / torture test - Is the Benchy still the top choice? 

Is there an "impossible print" that can be challenging for even the best FDM printers?

This is a nice overall tester: https://www.thingiverse.com/thing:2806295
This one is supposed to test a few more things than what a benchy does: https://www.thingiverse.com/thing:4575774

One of my new favorites is agepbiz's hinged 20mm cube, great test for making sure first layer squish/flow are well calibrated, plus makes for an amazing fidget toy
