I decided on tubs a long time ago because of the ease of cleaning and it was and is the easiest way for me to maintain proper humidity. When I got my first BP I was sold an expensive "kit" from a pet store that was completely useless for my BP. Looking back now that kit was useless for any reptile, it came with "reptile sand" for bedding. After that mess I learned that simple is the best way to go and I found it much easier to control heating from underneath than with any light setup. Basis space I would suggest a tank if you only plan to keep one BP and make a nice display, tubs for a collection.
