Theme development

Hi, 

While working on the custom theme development it is important to select the right base. As there are quite a few of theme base themes available to choose from am not sure which one to choose. I have come across two base themes: Bootstrap(3/5) and Stable 9, and am not sure which one will be the right choice for me as both Bootstrap(3/5) and Stable 9 have their own pros and cons.
