Will the 30-60 combination be a bit more "aggressive" than the 25-60 or 25-55?

You need to match the power head, bar length, chain pitch and type, and angles to the task.  Changing angles alone will have some effect and some trade offs.

Guys who cut all softwood might sharpen at 35*, but this could bog down the same saw in hardwoods.  Hardwood guys might go for 25*. So the 30* 'default' angle is often used for mixed/all around cutting.

Similar thing with the 60* grinder head tilt (although Oregon seems to be specifying 55* on a lot of their chains in their 'Maintenance & Safety Manual'). More tilt might be more aggressive, if your saw can handle it, but may dull quicker too.
