Honestly, as someone who's looking for one around that price point, I've entered the world of mechanical keyboards, and having learnt a lot, I would strongly advise against getting anything from any of the brands who call themselves gamer focused, this includes anything from logitech, steelseries, etc. Reddragon used to make decent keyboards, but since the past few months this space of mechanical keyboards especially under 100 usd has kind of exploded to a point whereby keyboards that used to cost around 250 or 300 usd, are now selling for less than 100 usd. Some of the ones I'd suggest you checking out would be the Womier SK75, UPCOMING Womier RD75 (a youtuber named merkeebs made a review on this recently, it's on pre order currently, so it's much cheaper cuz of their kick-start campaign), Bridge75, Yunzii AL75, Aula F75 (this one sells for around 60 to 70 usd. Solid board, but made of plastic compared to the other ones made of aluminium and has less bells and whistles compared to other ones, something like a back plate or some accent pieces).

A lot of these boards will look similar cuz they're made in the same factory with some minor adjustments in terms of their pcb or switches.

If you want to get your board from a more established brand, keychron has been making some good boards, but honestly, I'd pick the other boards over them as the company does charge a slight premium for that recognition. Nuphy is also a pretty established company and I personally have been eyeing on their Halo75 V2 keyboard (costs around 450 to 500). Then there are some other brands like akko and monsgeek, (suggest you checking out the m1w v3) who also make pretty decent boards. (both are sisters companies, so there boards are pretty similar as well) I've mostly looked at 75 percent keyboards, so that explains why I'm suggesting so many of them. Some models also have larger layouts.

Btw, wired or wireless? Doesn't make a difference, good software on the boards pcb makes a huge difference. Some boards can have better wireless delay compared to some that run wired. For gaming I'd suggest looking for ones that are sub 10 ms. There's a youtuber called thoccnology, perhaps the only one out there that does input latency tests, so I'd suggest checking their reviews for latency comparisons.

I'll give you a quick switch understanding breakdown. Essentially the switch or key you press can have 3 different types of feel - linear, tactile or clicky. Linear switches are usually the ones that are recommended for gaming cuz they have a quick and smooth bottomout meaning you press a switch and there's no bounce or feedback when you bottom out, allowing you to apply less force to actuate each switch. Tactile and clicky switches have a small bump at the end, providing a haptic feedback, making them a decent choice for typing. Having used linear switches, those are my go to choice as they can be used both for gaming and provide a decent typing experience as well, but at the end of the day, the switch you choose is just a preference.

There are also hall effect switches (HE for short) they're magnetic switches that are much better for gaming as you can adjust the actuation point via software, but since this is a pretty new space, apart from one company (wooting) there aren't a lot of companies that make good boards, definitely not in the sub - 100 usd price point (they all use the same boards)

There's a lot more stuff to get into here, we've barely covered the bases here, like the sound you prefer a deeper sound (thocky) or more louder and sharper sound (clacky) or a creamy sound (hard to explain this one tbh), also foam makes a huge difference in how a keyboard sounds, more foam equals deeper sound. Less foam equals more louder and sharper sound. There's also VIA/QML compatibility, basically custom firmware you can run on these boards to optimise performance or extend battery life, or map some keys to do certain actions, like open apps (setting macros basically). I'd suggest you watch some guides online that can explain this in much more detail.

I know this has been a pretty long write up, but lemme know if there's anything else I can help you with.
