I used MobaXterm for the better part of a year on a paid license. It was a reasonably good terminal, though I absolutely HATE the way they included the kitchen sink and then some in their app. Most of it was just cruft and they also seem to have decided not to use some standard things in terms of the GUI itself... rather than using one of the usual GUI toolkits, they seem to use something that is either home-grown or something I don't commonly see: wasn't so good on my high dpi displays.

I no longer use Moba and have replaced it with a combination of conemu (https://conemu.github.io/) for the shell improvement side (the larger rationale for using MobaXTerm in my case... MS shell being less that good), Windows Subsystem for Linux (for the cygwin stuff in MobaXTerm, and I just use SSH from there) and PuTTY Pageant for windows SSH agent and Bitvise for easy tunnels (https://www.bitvise.com/ssh-client). That may seem like a lot, but each part gets used for its strengths and its all really, really simple (and not all used at once.)

Totally agree, I don't know why there's such a blind spot for MobaXTerm. You can run up multiple copies of the free version to get around most of the limitations (I even do that with my paid for edition because I get better session tab management) .
