For me, that would be Secure CRT. I have yet to find a terminal emulator that matches its feature set. If you regularly manage hundreds of machines using various connection protocols (serial and ssh mostly in my case) It’s worth the $$$, and so far there hasn’t been any subscription nonsense. I liked using it at work so much I forked over the dough to have it at home.
None of the free alternatives do everything I need.
I’ll also mention a few iOS apps. One is Sun Surveyor. It’s an AR app that shows you the position of the sun, moon, and galactic center at any given time. The other would have to be Radarscope. It’s a weather radar app, but it’s a really good weather radar app.
EDIT:
This one’s debatable, but I use it all the time. Plasticity is 3D modelling software that attempts to bridge the gap between practical CAD programs and software meant for 3D artists like Blender. It’s not cheap considering Blender is free, but it’s buy once use forever, and at (I think) $150 it’s within reach of an individual hobbyist who knows what they want and is willing to pay for it.


I’ve never seen ads and I use the usual free TeraCopy at home. Are there supposed to be ads? (I don’t have a pihole or anything that’d be blocking the ads at the network level)
No, I could have just kept using free. But I was using it a lot and felt like I should pay for it, otherwise free software may not be available in the future. I think it was like $20.
Fair and reasonable. I don’t use it often and have nearly finished moving entirely to Linux, otherwise I may have done the same (its Windows-only).
