Hello,
A starter tortoise I wouldn't know, but the best advice I could give you regarding the African Spurred Tortoise is “space”.
If you do not have the ability to house it outdoors, you will run into issues with giving it a good quality of life. My sulcata is pushing 100 lbs and needs the ability to stomp around all day long, graze on grasses and weeds, and be able to sun and shade itself at will. Then of course, the winter months requires some type of outdoor heating that is safe and suitable.
If it doesn’t have the ability to do those things, he will figure out a way to do it on his own (Just ask my neighbors..lol).
As far as the Aldabra is concerned, the only reason that I never ventured it that direction is because of their size. I couldn’t even imagine having to move a tortoise that could get as big as they do.
All the best to your with your decision, you are definitely approaching it the right way by educating yourself. There are plenty of qualified keepers here that will help you learn.
