There's a similar war between logging and tracing. Tracing promises to give you everything you ever wanted to do with your logs and then botches it by sampling the data so you can't correlate anymore, or you don't sample and suffocate in data just as with logging but without the benefits. For debuggers it's probably the same: if they make the assumption that you need less than complete freedom in instrumenting the code, you will need print and if they don't assume that, they likely are harder to use than the language itself.
