Both were pretty influential. Roughly speaking I think a lot of people saw T2 and thought "wow, that looks really cool in a high-tech way" and a lot of people saw Jurassic Park and thought "wow, that looks really realistic". The silvery liquid terminator morphing into stuff was cool, but the natural-looking dinosaurs were cool in a complementary way.
