My faves: LSR gearless tuners. 40:1 ration (or something like that). These are locking micro-machine tuners with a linear pull. (micrometer like action).
Some people find them ugly but I find them pretty cool extremely practical - once an initial learning time has been experienced.
Yeah - they are great
You are definitely right about the learning bit- learning how they work and how a string is secured in
Some very clever engineering going on in them
Sadly too clever for some players
