Cherry G84-4100 or Noppo Choc Mini?

I've used both extensively (the G84-4100 from February to May 2010, and Choc Mini from August 2011 to present).

The Noppoo Choc Mini is superior to the ML4100 in almost every conceivable way except thickness (if you're concerned about that).

The ML4100 uses Cherry ML switches. These switches have a travel of 2mm, half that of most mechanicals. Think of them sort of like laptop keys. The feel would be pretty good, except for one thing: if you hit the key off center it will sometimes stick before going down. This leads to many typos and a generally frustrating typing experience. Also note that the keycaps are not interchangeable with MX keyboards, so you won't be able to use custom keycaps. It's not a *bad* keyboard, but unless your rubber domes are really, really bad it's probably not a big step up. Its only advantages are that it's one of the smallest desktop keyboards ever made, certainly the smallest mechanical keyboard ever made, and that it's very cheap.

The Noppoo Choc Mini uses standard Cherry MX switches which are preferred by almost everyone. You can get it in MX Black, Blue, or Brown depending on preference. The Noppoo is significantly thicker than the ML4100, but it's only a little bit bigger in terms of length and width. It's also more sturdily built. It also has built-in macros for volume control and such, and a simulated number pad, and it has a button that switches the Caps Lock and Ctrl keys.



I vastly prefer the Noppoo to the ML4100; you can see this in that I only used the ML4100 for three months while I've been using the Noppoo for over a year.

Out of those two, definitely the Choc Mini.

If sturdiness is what you are after, you might also want to look at the Deck 82. If money is an issue, the TG3 BL82 is similar to the Deck and a lot cheaper, but not as much rollover. I don't know how obtainable either will be in your country, however.
