In my opinion it's not the keyboard itself but switches, keycap profile and keyboard chassis to some extent. I like switches that are tactile, crisp in both sound and tactile feedback, and not overly hard to bottom out. From sound perspective the most pleasurable combo for me was SA keycaps + Kailh BOX Jade switches which produce deep and crisp click sound. I also tried Cherry and OEM profiles and I absolutely hate Cherry profile both in sound profile and just how short they are. Having said that I think OEM (for instance the one found on Pok3r keyboards) suits me perfectly and even after buying some GMK and SA keysets I keep typing on original Pok3r keycaps. I just love the material and profile. Coming back to switches BOX Jades are not the best experience because they work like a binary switch, it's either pressed or depressed. Due to the sharp force curve and light spring it's hard to have any travel, it just bottoms out immediately after overcoming the bump. BOX Navy switches on the other hand are too heavy but typing experience is nicer. I found a good middleground in Kailh BOX Pinks with Kailh BOX White/Jade springs. They are easy enough to press, they do not tire my hands after typing all day and they still produce nice sharp click. I'm using them with OEM keycaps and that's the best experience I ever had and I cannot match it ever since I started using this combo.
