In my experience, I would avoid wireless mice and keyboards. Every wireless mouse Iāve ever tried has always had lag. Even if itās just minuscule lag, I notice it. That was as of last year when I tested a new wireless mouse or two.
LOL, while I was posting, I see @breeminator commented that their wireless lag is actually less than wired. Interesting. Maybe you have to spend a lot of $$ to get over the lag hurdle with wireless? Admittedly, my wireless test have been with sub-$50 mice, so maybe you get what you pay for. I just always assumed that lag was inherent to the technology so spending $100+ on a wireless mouse would have similar lag.
- Personally, I also donāt like having to worry about my mouseās/keyboardās battery dying on me, needing replacement on occasion, or slowly depleting over time. (Wouldnāt the responsiveness diminish as the battery drains, too?). So I prefer wired for these reasons, too.

I have a wired āLogitech G Pro Gaming Mouseā and really like it. Really smooth, responsive movement, and the braided cable is quite flexible compared to old-school cables, which is nice to help move it out of the way.
As breeminator said, I agree that the smooth movement and accuracy of gaming mice is worth it. Cheaper mice are fine for work, but for gaming/home, itād now be weird for me to use a mouse without good DPI and polling rate.
The DPI switch on my mouse (located below the mousewheel) has come in handy. It has four customizable sensitivity presets to toggle through; to be able to change sensitivity on the fly.
- Comes in handy for certain games where the game changes mouse sensitivity on you; when you, say, go into a vehicle after running around. An older game Iāve played, in particular, really slows down the sensitivity when entering a tank, but I just click my DPI button a couple times to increase sensitivity to the max preset I made and Iām good. After exiting the vehicle, I hit the DPI button a couple times to put the DPI back to what I like.
Regarding DPI and polling rate, itās pretty incredible how sensitive you can make gaming mice. I could see some elite players across the gaming industry being able to crank up the DPI beyond what I use and do great with ultra-fast turning and such. I have my personal limits 
I also like being able to move my mouse pointer across the screen by moving the mouse a couple inches (literally) on my mouse pad, without having to lift my mouse up and repeating that motion multiple times. I can do this with my gaming mouse; which, over time, may help me avoid carpal tunnel syndrome since Iām not moving my hand/wrist as much.
- At work, though, with the inexpensive (non-gaming) mouse, I find myself having to crank the Windows 10 mouse settingsā Pointer Options sensitivity all the way to the highest and itās still not fast/sensitive enough for what Iām used to experiencing on my home PC with gaming mouse. The relatively poor polling/reporting rate also probably doesnāt help.
I just checked on my home PC and Iām able to have the Win10 setting at a reasonable mid-point level because of the gaming mouse, which I have set to a default of 2550 DPI sensitivity & 1000 polling rate. Thereās no way I could have this setting at the mid-point at work:

As for keyboards, the main problem Iāve had with non-gaming keyboards is sometimes they donāt let you press multiple keys at once to register the keystrokes you want and in the order you want. So, for example, if youāre playing a FPS game and need to hold ALT+SHIFT+W down to do a particular move (which some do), some keyboards wonāt let you do that, if they only allow two buttons to be reliably pressed at once.
- Iāve had a couple other things not work or act weirdly, just canāt remember offhandā¦ but it was usually tied to the keyboard not allowing more than like two keys to be pressed at a time and/or needing to hit keys in a certain order if you needed to hold down 2 or 3 of them.
- A higher ān-key rolloverā value on keyboard specs lets you press multiple keys at once without issue; I doubt youād need to hold more than 3 or 4 keys at a time, but youād want it to be possible and reliable if you did. I have a Logitech that has gotten the job done for me.
- I think responsiveness may have been an issue on some keyboards Iāve tried, too. I donāt try a lot of keyboards, but the issues Iāve experienced are with the generic ones that get included with PCs you buy.
Thatās just my experience, but I think itās worth it if you can. Even low- or mid-level gamer peripherals might be okay. I donāt have high-end peripherals by any stretch of the imagination. The Logitech G110 keyboard I got 10 years ago is still going strong. And there were definitely mice a lot more expensive than what I got.
Wow. Sorry for the wall of text :-/ Didnāt intend for that to happen.
