To me V21 is the last of the great BobCADs. I've been using V20, which is nearly identical, for many many years. I also like my G-code right in front of me as I'm creating and modifying it. For all practical purposes, I use the CAM side of the software to fill in all my X - Y - and most Z coordinates, where I do the rest of the G and M codes with copy and paste. I do use Profile a lot also. With two very simple settings (arc radius and lead in distance) it makes perfect cutter comped tool paths with just a few clicks.
I got V23 which is about where they changed everything. I tried and tried but never got it to stop cutting air maybe 40% of the time. I'm certain that the new versions run circles around V23 but still, I've never been able to get past the ineptitude of the software. I'm sure some of that was me too, but V20 has allowed me to make some pretty great parts over the years. Many times on large logo engravings, I'd use V23 to fix the BobART tool paths and create the pocketing code, but then back plot the G code in V20 so I could see and remove all the excess air cutting and wasted moves. I do wish V20 had simulation that was worth a damn. Other then that though, no complaints.
I have to say that most of the post processor stuff you see posted around here is full of tons of excess junk, and so many of the adaptive tool paths you see on youtube look like a huge wastes of time and machine power. I have nothing against HSM, but most of what I see makes me cringe. Who has the time to run tool paths like that? Maybe part of it is because of all the low rigidity and low power machines being made and used.
Anyway... I'd like to try the latest BobCAD and possibly someday I will, but reading your post I sensed a kindred soul to the older versions that have worked so well for so long. I'd be curious to know if and/or when you ever start to prefer V32 over your V21. Wondering if it's possible, and after how great of a struggle.
