Best iridium spark plugs these days ?

2009 Wrangler.

I guess they are all a bit pricey. Whose is best, meaning maybe last the longest ?

NGK Iridium is all I’ve been using for years now. Probably 15 years. No issues

I still run Denso in everything. But I may be a little prejudiced after 28 yrs. as a 'yota tech and never saw a plug-related failure from an ND plug.

My 05 300C still has the plugs it was born with. 180,000ish on the clock...
