With the different types avaliable, which type would give above avg performance ?
The thing is that a spark is a spark. No plug is going to be bigger or better or longer or brighter really.
Thin electrodes last longer and arguably are better for ignition than fat ones. As for the triple and quad core plugs, you still only get one spark from them so leave well alone.

Every now and again someone post something thats just nonsense and and this is such a time. There is no easy way to reply
Im sorry but I get really annoyed when people post a sweeping statement that is simply wrong .
Lets hope nobody reads it and puts crap plugs in a hi power engine.
It is true that on some engines - usually standard tune low power ones , you can use pretty much any plug - same as you can use low octane petrol and cheap oil.
On high power engines all the parts are critical -
You can no more use cheap plugs as you can low octane petrol or cheap oil.
if I (or t9 for example) put cheap plugs or low octane petrol in our engine we would be rebuilding it as soon as it ran high boost for any lenght of time.
Spark plugs are an absolute crucial part of the set up on a tuned engine.
On Rb26s (which is what I know about) virtually everyone uses NGK irridiums .
I pay under £50 for a set of six so there hardly expensive with petrol at £1.40 a litre .
Personally I have heard of densos breaking down quite often on high boost ( when spark really is important) and as NGKs are so cheap compared to the cost of the petrol we use I would only ever fit them
