Don't fear dry yeast! It's cheap and reliable, and you don’t need to make a starter! I use Nottingham all the time, with great results. It's also a better attenuator than WLP001 or other liquid yeasts. Attenuation is close to 80% regardless of mash time or temperature.
I've read someplace that Nottingham ale yeast might actually be the ancestor of WLP001 and US-05! I'm not certain if it's true but from what I recall, it was pretty compelling evidence. So as far as equivalency or similarity, all three are very close. Nottingham gives off a low fruitiness and tartness, similar to apple and banana, but if you keep it under 68 F it is a good clean yeast, great for any American styles. It also ferments all the way down to 55 F so you can keep it as clean as you like. Very versatile. Don't fear it.
