One factor is whether or not you mount your own tires, or you at least know a guy.
That can change the cost/hassle equation to the point where it's worth getting something more expensive but longer-lived.
Another factor for me is expected tire age. As my stable grew to three bikes, I found that I was riding the GS850G less, totaling maybe 2,500 - 3,000 miles per year. So an Avon RoadRider on the front that lasted 12,000 miles for (normal people get a lot more) would be four or five years old at replacement, which was unacceptable. (My personal hard limit is three years.)
So I switched to the Shinko 230 or 712 (can't tell the difference between these two from the saddle) and spoon on a fresh set every year. They work fantastically wet or dry. Again, normal people usually get around double the mileage I get.
There are several brands that make good tires and only a few bad tires.
These are the bad tires, the ones I warn people to NOT install:
Kenda - Just no. Never. Ew.
Bridgestone Spitfire - Nope. Short-lived and turns evil as it wears. Bridgestone's other vintage bike tire choices are quite good (BT-45 & 46), but the Spitfire is badly outdated.
Dunlop 404 - Also short-lived and turns evil as it wears. It's cheap and looks good to some, but not worth installing. Depending on your tire sizes, there may be other Dunlops that work quite well -- for example, the Dunlop Elite 4 is quite good and wears like iron, but is only available in 16" and 18" rears.
I'd also avoid the whole category of "vintage reproduction" tires for a bike you're actually going to ride.

If you just gotta have that particular look, understand that you're giving up a lot of safety and performance, and these can be damn expensive. We're lucky to have access to some remarkable modern tires nowadays, stuff racers in the '80s would have given a limb for. There's no reason not to take advantage of that progress.
And for research into what's available, American Moto Tire has a list tires by size tool that's fantastic, and they're a great tire supplier if you mount your own or know a guy. Excellent prices, fast shipping, and they're probably one of if not the biggest so things tend to be fresher:

I've also been very happy with Rocky Mountain ATV/MC; they have a 5% back program that makes them come out the cheapest most of the time when you factor that in, and with their warehouse in Kentucky, I normally get my goodies here in Indiana the next day.

Yes, they have street tires along with lots of dual-sport goodies for my KLR.
