The right answer is always "whatever guitar is gonna make you play more".
For example, I lately bought my first headless guitar, an Hils HNT1 to be precise. I didn't get it for the sound, I already have more than one telecaster iterations, I got it as a couch guitar and for when I travel. It's so light and compact that is impossible not to pick it up every time I walk by it.
If you want to learn more instead, get yourself a cheap building kit, a fret rocker, a fret-end file and a Frtlzr system. Follow a tutorial somewhere on setup and basic fretwork and make the best you can get out of that guitar (I assure you that is much more than you expect).
You won't spend more than 300$ and you'll end up with another guitar, a great learning experience and some tools you can use to get the most out of the guitars you already have.
