What spark plugs do you recommend for my Opel Astra?

I presently use 3-pin Borch spark plugs on my car. I really don't know if the vehicle would perform less if I change to 2-pin or 1-pin since I find it difficult getting the genuine 3-pin Borch spark plugs to buy. Are they any other good brands of spark plugs.|||Even though they are difficult to find I would stick with the genuine (original equipment) part. The tree pin Bosch will probably perform the best out of all of the others. It's hard to beat the original.|||get sum good ones
