Which gear should I be in?

[Ten1nis]

While driving my A around town I many times find myself in the situation where I will lug the engine slightly in 3rd or downshift to second and rev the engine slightly to get back up to speed. Which is more preferable for the 4 banger? I've owned some 4 cylinder Porsches in the past and you always want to keep the revs up with them, but that doesn't seem that the stock A engine should be run like that.
