What's the best captcha regarding accessibility?

[burningChrome]

None.

There are no "best" version of captcha. I've worked on several large scale projects where captcha was floated and then quickly abandoned in favor of other methods like Honeypot or using other methods to weed out bots and other 3rd party agents.

If you have to use captcha the least worst are probably reCaptcha V2 and hCaptcha for accessibility.

What were the chosen choices? Curious to know

I'm OK with reCAPTCHA, but uh... Just not a fan of Google!! I'm an expert reCAPTCHA solver.

Brave PoW captcha maybe? Because it requires no input/interaction from the user.

I don't understand why POW solutions aren't more popular.
