I see the wiki agrees with you:

Sort them by activation force, and it's like MX green is essentially the clicky peer to linear and tactile grey.
But they really don't feel that way. Time to dig out some switches…
Okay, so I have one switch of each grey – one linear, one tactile – and they're easily the heaviest MX of the whole lot. (Well, putting the historical "super black" to one side as they're a whole other story. And I don't have one to play with yet. But I do have MX red, black, blue, brown, clear, white, green, both greys and a Nixdorf black and MXLOCK.)
A spare MX green can't stand up to the greys. Pressing two switches together, stem to stem, is a simple way to visualise this. You can see which one caves in first, and get a visual on how the tactiles and clickies stack up against linears. The green is just blown away by my linear grey. But a regular MX black is a much closer match.
I'd rate MX green as the clicky equivalent of MX black. In fact, several switches are right in that zone: MX clear and MX lock are about the same weight as a black, too.
There's an equivalent group among the light switches. MX blue is close to MX red, and brown is right in that zone too.
The greys meanwhile are another level of spring weight again, right up at the top of the whole range. My greys balance each other closely, but dominate any other switch paired up against them. So there is no (currently available) clicky equivalent to either MX grey.
Note that none of this was objective, scientifically controlled testing. Not even coins were involved in this experiment! But the pattern is quite striking when you have the switches spare to try this for yourself.
