Geotuning Tier List and Guide! (ONI: Spaced Out!)

I have about 2100 hours of experience playing Oxygen Not Included and thought it would be a good idea to make a tier list of which Geysers I would prioritise Geotuning. The Geotuner machine lets your duplicants supply a material and do research to boost a Geyser's output volume and temperature. This list is based on which Geysers are most resource efficient to Geotune as well as specific pros/cons you might get from Geotuning them.

This is quite subjective and somewhat theoretical as I haven't gotten to every Geyser yet in my playthroughs, so feel free to let me know what your thoughts are on this and what you generally prioritise or ignore when it comes to Geotuning. This video is related to the previous Geyser Tier List here: Geysers and Vents Tier List! (ONI: Sp.... I also provide some updated thoughts on that list based on game changes since that video was released (which is partly why this video is longer!)
