Tortoises are kind of cuter and easier maintenance. I used to be crazy about both. Tortoises are pretty expensive, while turtles are way cheaper. Turtles need huge tanks, 10 gallons for each INCH of their shell. Turtles need heat lamps, UVB, basking platform, and filters. Tortoises can live happily outside in a pen, and during the winter they will hibernate.
