There are no best openings.
You are missing a lot of fine moves like 2.Bc4 e.g.
Those are my favorites
2 Ke2 is a bad second move
Nevermind this is the best opening for white
Nc3 is hands down Top 2 best for e4, e5
Nf3 is even better than Nc3
This:
2. Bc4 Nf6 3. d3 is my favorite continuation. At my level of rapid it usually transposes into Giuoco Pianissimo.
