Ruthenium VS Iridium Spark Plugs, NGK said Ruthenium = no advantage EXCEPT Maybe? Denso Replacements

To see IMPORTANT pricing corrections made to video, read my "pinned" comment (at the top of comments section).  This video and description is 100% my opinion of the information that NGK tech support shared with me during a phone call on 10/1/21.  After much googling with vague results and watching other similar (inconclusive) Youtube videos, I got aggravated at the almost mythical why that this spark plug seems to be marketed and understood by the general public.  As such, I decided to go straight to the source and grill the NGK tech support staff.  In the end, no "grilling" was necessary and Tech Support was very forthcoming with the EXACT answers that I was looking for. THERE ARE SEVERAL PRICE / VALUE RELATED MISTAKES IN THE VIDEO. TO VIEW THEM, TURN ON  "SUBTITLES", "CAPTIONS", "CC" or "Close Captions" -- and CHOOSE "ENGLISH (United States)" OPTION!!! -- & NOT THE "AUTO GENERATED SUBTITLE" OPTION!!!  For those who are unaware,  You can find the subtitles section if you hit the gear icon in the bottom right of the video as it plays ON YOUR COMPUTER -- OR -- the top right of video playing on your PHONE (in the hamburger menu).My personal notes on this phone call are expressed verbally in this video and also follow (in written form) here...  "I called NGK Tech Support on 10/1/21 and they said that the marketed “extra life” that Ruthenium provides is as compared to their “basic” iridium plug (that has a 60K mi change interval).  NGK’s Lazer iridium plug has a 120K change interval.  So (assuming the plug you are replacing has a 120K interval) there is supposedly ZERO advantage to going from iridium to Ruthenium other than it is a little bit cheaper.  I asked the rep if she was ABSOLUTELY SURE about her answer because it did not sync with NGK’s Marketing material (promoting extended life) and one random (internet board) post that said ruthenium might go 2x longer than iridium.  She said she was ABSOLUTELY SURE & That the 2x longer life claim was as compared ONLY to the basic or "LOW END" IX iridium that NGK sells.
