OK. Using your link and your search criteria, I find one tire, the Yok Avid H4, that isn't offered in the 55 series. So you are right. You get one more tire to choose from.
Here are the other tires that come up in the 60 series search:
Tire Rating Price 205/60-16 Price 205/55-16
Bridgestone Potenza RE92 H 81 81-83
Bridgestone Potenza RE92 V 97 119-130
Dunlop SP Sport A2 H 73 75
Goodyear Eagle HP H 74 86
Yokohama Avid H4 H 59 n/a
Yokohama Avid T4 T 68 76
Yokohama Avid V4 V n/a 75
The savings available in going to the tall size vary from $2/tire for the Dunlops, to $22/tire for the V-rated RE92s. But we've already said we don't need a V-rated tire in the winter. So that leaves the H-rated RE92 at 0 to 2 bucks difference, the Yok T4 at $8, and the Goodyears at $12. That means the most you'd save in putting non-spec tires on your car, if you really liked the Goodyear Eagle HP, is $48. Not quite half a DMD.
So, minimal savings, no greater selection, and no measurable benefit. (Unless you are shopping used tires, but that's another story). Add to that taller gearing and a messed up speedo...
My humble advice is to use up the tires you have (since they work for you and the money is spent) and then replace them with OEM-sized tires.
