Yeah, but the problem with asking lots of people their opinions is you'll get so many different answers that you are right back where you started: not knowing how to choose from among lots of options.
FWIW, the answer I'd pick isn't on your poll. I'd pick a 17-70 zoom for situations where I didn't want to mess with multiple lenses, and a set of three primes (wide, normal, telephoto) for situations when I didn't mind. So I'd have *either* the zoom *or* the three primes with me; seldom if ever both.
Variations might include the 18-55 instead of the 17-70 to save money/space/weight. The 18-55 is actually what I have, but if I were starting over I'd be looking at the 17-70's. I suppose some would pick a real superzoom over this, but if I'm going to spend that money and carry that weight, I think I'd rather have a really good 17-70 that covers 90% of my shooting needs. But realistically, the three prime set makes me pretty happy most of the time. The zoom is just for occasional use, so I think the 18-55 is actually adequate.
Which three primes? Well, the 21+40+70 set makes a really good starting point. If you feel you want longer than 70 for your telephoto, then get a 90, 100, or 135.
