I had a redfoot for a few months at a time when I didn't know much about tortoises. I've had russian tortoises for about 6+ years now.
I find russians easy and interesting to keep for number of reasons:
1) They do well in a low-humidity environment. My house is always very dry. Humidity loving animals seem to suffer, even with regular spraying, proper substrate etc.
2) They are very tolerant of temperature and humidity variations. I wanted to keep my tortoises outdoors as much as possible, and russians do very well for 6-7 months of the year here in Missouri. They can tolerate lows in the 40s and highs in 100s (with appropriate hide boxes). Just can't leave them out in the rain AND cold.
3) I have a small house so I need a small tortoise
I hibernate mine, but it probably isn't necessary. It can be difficult to find captive-bred russians, although there were plenty of baby russians for sale on kingsnake this year.
