Multiple Blocks vs. One Robust Block

There is no right or wrong answer here, generally you want to focus on creating content models that empower your specific users. If the users prefer to use a single robust block over multiple more simple blocks that is fine and vice versa. Below are some pros and cons of each.

Multi-block

Pros:

• Multiple blocks give a more simple and more content focused choice. Users only have to focus on inputting content once a block is chosen.
• Users lets the code dictate the blocks for them rather than the user dictating the blocks.

Cons:

• Users need to be taught what many different blocks do.
• More block choices for a user to build from, if not trained properly on what each do, can lead to possible front-end errors. 

Single Block

Pros:

• You empowers users with a bit more styling options, rather than just being content focused only. 
• One block choice means less clutter of blocks. if you also have many other blocks to choose from.

Cons:

• More fields to input, which leads to more errors, which leads to possible front-end mistakes. Test environments can help solve this.

Depending on the complexity of the blocks, single or multi block could provide more benefit than the other. The more complex a single block grows, then using multi-blocks that remove all the complexity could provide more benefit. If the single block only has very minimal differences between options, a single block could provide more benefit.
