I haven't done any side-by-side comparisons to taste the differences between all the different dry yeasts, but I think most people will agree that US-05 is the "old reliable" one that people really like to use. It's cheap and effective and clean for all American styles.
I could almost say the same for Nottingham ale yeast, which is the old "old reliable". It is typically a great yeast as well, when it works, but a handful of times over the years they have run into quality issues (i.e., yeast was dead on arrival). When it works it works great. When it doesn't... could be 5 gallons down the drain. That being said you could always keep an extra pack or two on hand for emergencies. It's cheap insurance.
