Coil Question

[mrfirepro 127 1 Cars]

Have bought an unbranded non OEM coil (£26 iirc) which I was fitting today. On comparing the two, the one that was on my car (Bosch) seems a lot heavier and this got me wondering.

 

Should I scrap the cheap coli and go for a branded or even OEM coil or is it just one of those things that providing it works it'll be OK. I am doing everything to the best level I can and dont really want to compromise too much anywhere.

 

If I should go branded, which are best?

Clean up the Bosch and put it back is what I would do.
