React PropTypes vs Unit Testing

PropTypes of React allow to create custom validators. For example, for the value:

[{propOne: 'string', propTwo: 2}, {propOne: 1, propTwo: 'value'}];

It is possible to validate whether:

• this value is an array
• this value consists of objects
• objects are not instances of arrays
• this value's length is 2
• each object of this value has exactly 2 props
• the value of the first prop of the first object is a string
• the key of the first prop of the first object is propOne
• a.s.o for each value

Should I write this kind of prop validation using PropTypes or it is better to stick to shallow validation with PropTypes and dedicate most of the job to Unit Testing?
