"Just genuinely curious why the Frigidaire Unimatic is so sought after?"
Several reasons:
Unique vertical pulsating agitator/transmission only GM Frigidaire designed.
Out of the 5 transmission designs Frigidaire produced (Unimatic, Pulsamatic, Multimatic, Rollermatic, 1/18) it was the most durable and reliable one out of the mix.
The only design that spun 1140 RPM's during the spin cycle (one of 2 top load washers that ever spun that fast with the exception of the very early GE's).
They are very rare as the last one rolled off of the assembly line 66 years ago, badly tangled items bad if not carefully loaded, were tossed due to the very small size of the tub 10+ years later, parts availability, and finding a repairmen capable of properly fixing them.
I talked to a repairmen in his 60's 20 years ago who used to fix them and he said parts were already getting tricky to find by the 1980's for the Unimatic and Pulsamatic washers.
