Any upgrade from a Skerton is worthwhile ;) The Skerton grinds erratically, being more a crusher than a grinder, and it's so. terrifically. slow. On the other hand I suspect a Fellow Ode is more than you need or want.

Knowing little about you, I have to make some guesses. It sounds like your tastes run toward what a coffee hobbyist might describe as — forgive me — uncomplicated coffee. The Ode is more for people who want to tinker with the parameters of their brews, searching for flavour nuances. It has flat burrs for one thing, which may require alignment: partially disassemble, install shims so the flat burrs are precisely parallel.

A Kingrinder would be a big improvement over a Skerton, and the K6 is a particularly nice choice from their lineup. I think you would be pleased with a K6 for a very long time. Timemore is another well-received brand. Personally I use a 1Zpresso hand grinder. Same idea, some improvements.

In electric grinders you'll see the Baratza Encore recommended widely for beginner enthusiasts. I have used and don't like the Encore. I might recommend a Turin SK40 (though not at full suggested retail price!) or a Lagom Mini for you in electric (though I have never used either). If it's the toil of grinding coffee in a Skerton that wears you down, any of these choices will be a refreshing upgrade.

While I'm at it, I might mention the Moka pot for brewing, in case you are unfamiliar. It makes stronger coffee than pour-over, though still weaker than espresso. Personally I prefer pour-over, in a somewhat complicated style.
