Is there any down side of using comparison operators on strings?

[makiwara]

I see no source on the internet who mentions that strings can be compared by operators like =, >, =>, etc

However, I found out that they work pretty well the same like numbers
- the smaller means it's earlier in the alphabet
- and of course you can use logical operators on strings as well like "and" or "or"

So what about comparison operators, is there any down side?
