I'm am aware just using it for design purposes only. I just have a passion i guess you can say for home design and want to design my own and build it one day. I've just been looking for a product to store my ideas mainly

I'm a Civil Engineering Student and I've been looking for a great software like this one for awhile. I mainly want the software to create and keep up with my own home ideas and maybe even some friends who have asked me to design homes for them. My question is which product should I buy the Architectural or the Pro? I feel like the Pro will be a great investment but at the same time i believe the architectural will serve my main purpose.
