They are both great I love ackies and tegus. For a beginner or size wise, you can't go wrong with ackies as long as you follow the caresheet. Argetina tegus are bigger and takes more space. I love them both. Don't look at the price since ackies are very rare and can't go wrong with them. You can always save more money and purchase what you really want. Never settle for less. Good luck.
