Welcome. Depends on your taste and what kind of work you do with your keyboard. If you use your keyboard for games you should point to a smoother linear keyboard as far as the one you have doesn't make you feel comfortable. There are quite a buch of smoother MX based switches with contactless sensing and some other advantages. If you work with your computer, for example coding or writing, a tactile switch with hysteresis is more desirable. You can either get a silent or a clicky keyboard, but the clicky spread of options is bigger. A great keyboard for coding without going crazy is the Unicomp model M or any used IBM model M you can get.
Said that, if your keyboard make you happy and you're efficient with it, there is no reason to get mad. Good luck

I think that if you are happy with your current keyboard then there is no real reason to get another just yet. As for the difference that you'll see, the quality often goes up with the price. If you are looking at the generic brands on the market, you will likely be looking at Cherry switches. Some of their switches are alright, however, you likely won't be seeing a huge difference in feel.

I mostly agree with the other replies. If you like what you have stick with that. I have a red dragon board with mx blue clones (I think they are outemu but I don't feel like checking) and it is pretty decent. Personally, I like alps switches MUCH better than Cherry MX or clones so my daily driver is a Focus FK-2001 with white Alps but it is a preference thing (I also REALLY hate the hysteresis that comes with clicky Cherries). If you are just looking to try something different then I would suggest trying either Alps or Kailh/Novel Keys Box switches. I just got a board with Box Navies and they are really nice (if a little stiff for my liking). If you end up trying Alps you should try to find a clean board with them. I have had a couple boards which I would call unusable solely due to the condition of the keyswitches so keep that in mind.

Another option is a board with Matias switches. They are basically the modern version of Alps (big asterix). They are nice but in my opinion a nice Alps board beats a nice Matias board any day of the week.
