Mesh Baker vs Draw call Optimizer?

[gurush]

Hi guys, I am about to buy one of those assets but confused on what to buy.

The main purpose is to reduce the draw calls as well as batches for my Unity project.

Mesh Baker:

Mesh Baker | Modeling | Unity Asset Store

Draw call Optimizer:

Draw Call Optimizer - Just One Click | Utilities Tools | Unity Asset Store

Are they the same thing but mesh baker let us do mesh combine and texture atlas manually, while Draw call Optimizer automatically proceeds the stuffs?

Thanks in advance!
