That casual sort of 'do what feels write' method has worked for me on three books so far. I'd love to be able to stick to a word target, but I've never been able to do that - I can't MAKE myself write 2000 words anymore than I can MAKE myself know the square root of 765. I'd go completely looby-loo within a week.
I think this is true, but I also think there is some number of wrods you can make yourself write each day, if that's the way you choose to go, just as you can make yourself know the square root of sixteen, or even sixty-four, without any undue effort.
The number might be 100 words, five hundreds words, or whatever, but it's there. When going the word count route, the trick is to find your own magic number, usually one that's high enough to take some time, but low enough to be reachable day in and day out for who you are as a writer.
I've found my own magic number is 2,500 words. I
can write 12,000 words per day, but I can't make myself do this day in and day out. But 2,500 words? Yes, this I can make myself do day in and day out almost forever without burning out.
For some writers, daily word count goals work very well, especially if they find the magic number they can make themselves reach each day without going bonkers. I think the best way to find this number is to just write for a couple of months without worrying about it, and then looking back at what you've done.
At any rate, time per day works best for some writers, words per day works best for others. And then you have the writers who don't worry about either because every last spare minute they have is spent sitting at the keyboard writing. From my experience, these writers do extraodinarily well, and often succeed quickly. They don't have to be told about time or word counts because they can't wait to get to the keyboard, and you have to drag them away so they can eat and sleep.
