My current favourite is Corsair. I gave up on Logitech for both mice and keyboards. Their quality has really gone down within the last decade or so, especially as they've only gotten more expensive. My last logitech keyboard, was perhaps the G110, and I remember being very disappointed with it out of the box as the keys were sticking and it wasn't a great feeling, and it was not an inexpensive keyboard. I felt that at that price, the quality just wasn't there. It's a price/quality ratio, and when the price is higher due to where you live, sometimes it just doesn't make it worth it.
I now have an aluminum body Corsair and it's quite solid and the quality much better, and I think I paid less than I had with the G110, and my mouse is also Corsair.
And what I like about Corsair, is that once I set up the settings and saved them to their onboard memory, once I moved over to my new computer I didn't have to set it all up again. Bonus for not needing to set up an account to use the app.
