Well I cannot compare Ural or BESM to the foreign analogs, but given they were exported worldwide, they were not that bad. The ЕС ЭВМ was a copy of an IBM-produced prototype so it was not larger nor smaller than IBM-produced analogs.
You can also consider a Soviet "pocket-pc" Elektronika MK-90/92/96.
It had a 16-bit processor, graphical display and embeeded BASIC interpreter.
You could also attach it to a dock station and connect to an external display and printer.
Of course this thing was much more expensive than the БК-0010 which had a similar processor and amount of memory.
