Essentially, the Razer Blackwidow V3 is the wired version of the Razer Blackwidow V3 Pro, which is why it costs less, around 135 euros compared to the Pro model's 225 euros. It has a very good build quality and decent ergonomics, as it comes with a wrist rest and can also be adjusted in tilt, in two levels, for a more comfortable typing experience.
It comes with two types of switches, the Razer Yellow and Green. The first ones are quiet when pressed and do not require much force to activate, and they also have a short activation distance, making them ideal for gaming but not as good for typing, as it is easy to accidentally activate the wrong key. If you want to hear the click confirmation every time you press a key, then you should go for the green switches, which are equivalent to Cherry MX Blue. Note that these switches are clicky but ideal for typing.
The Razer Blackwidow V3 is definitely not a budget mechanical keyboard, but it has high build quality and offers a choice between gaming and more office-oriented switches (Yellow and Green). I found it very comfortable during my testing, and the Razer control program, Synapse, is quite good and you won't need a PhD to work with it (unlike the equivalent program from Corsair).
I would have liked it to have a wrist rest that attaches either magnetically or through a mechanism on the main body of the keyboard, and also to come with a detachable cable. USB passthrough and possibly headphone jacks would definitely be welcome, although they would significantly increase the size of the connection cable.
For those of you who don't want a full-size keyboard, there is also a Tenkeyless version available, without the numeric keypad.
