Porting limiting to street is good...
And I hear good claim with streetport & 2mm apex combo is more reliable.
3mm apex seals have been in controversy in terms of adverse housing damage effect more so than performance that it claims..

Porting expands your intake and exhaust ports to a larger size than normal allowing more air to flow.
Larger apex seals supposedly seal against the rotor housing "better", conversely I've heard that they damage the rotor housings, and can go out a lot easier. I don't know a lot about the size of teh seals themselves.

As AusT said 3mm was to "sweep" thru rotor housing tighter to give more compression but in that process also jeopadizes housing damage...

If the prices are low enough, they'll last you long enough to warrant getting them now.
