I had mentioned SecureCRT, it is my daily use ssh
client. But if we
want to focus on more vintage software, my favorite terminal emulator
is ProComm Plus, made by Datastorm. As it happens, the two original
authors/owners wrote it while living in my area (university). I grew up
using that one, and it is still installed on my move-around-rack-on-
wheels system that provides services to other machines in the
collection (PUTR, etc).

Procomm was the first terminal program I used that was easy to understand and work with.
Of course I was using it mainly to dial BBSes at the time. I stayed with it for a few
iterations until I switched over to Telix and finally Terminate (interestingly
Terminate's web site forwards to
protonmail.com now). There was also Windows version
of Procomm which was slower and had more bloatware features while being less reliable. The
last probably had to do more with the HW then the SW though. Downloading under windows
while multitasking was always a crap shoot! Plus you could not add more protocols easily
(e.g. HSLink) since most protocols were written for DOS and not a windows environment.
With windows I actually started using ZOC which seemed to run better and more reliably. It
was great for a bit but once the internet became a "thing" I walked away from
most of the terminal programs.
SecureCRT is great and very full featured. I use a very much older cousin called CRT with
my headless mini Linux server. Although I have also used it for such mundane tasks as
accessing APC UPS consoles and Netgear equipment, and even dialing a BBS. It does support
color, but at least for me, it has never been very accurate.
