Is there any difference about thread safety strategy between accessing member directly and accessing by self.name?

I have the code below.
I'm wondering that does the self.value and _value have some difference about thread safety strategy?

//temp.h
 @interface Temp:NSObject
 
 @property(nonatomic, strong) NSInteger *value;
 
 @end
 
 //temp.m
 @implementation Temp
 
 @synthesize value = _value;
 
 - (void)someMethod:(NSInteger)someValue {
     self.value = someValue;
 }
 
 - (void)someOtherMethod:(NSObject *)someValue {
     _value = someValue;
 }
 
 @end
