What type of plugs do YOU use? Options

[ActionClaw]

When I was at the auto parts store today I noticed there was a sale on (both Platinum and Copper Classic) SplitFire Spark Plugs. It was a great price so I figured I might as well put in a new set. I told the salesman what I needed. When I did, another guy behind the counter overheard me tell him "'95 Celica" and kinda mumbled a warning "I wouldn't do it". I wasn't sure he was talking to me. I looked over, he stopped what he was doing and repeated "I wouldn't do it". I asked what he meant and got "I wouldn't put those plugs in a Celica. NGK." Someone else there agreed; NGK only.

I've see some others here use NGK, there's been talk about E3 Diamond Fires, etc. Sure, there are differences but I didn't think there was that much of a difference between one brand and another. Besides, I'd heard SplitFire's were supposed to be good plugs?

Anyone else here ever hear this (NGK only)?
Why would NGKs be so much better or more appropriate for use in a Celica?

Is this Toyota's recommendation or just opinion?

Toyota's tend to like factory parts. NGK and Denso make factory parts, people have found their Toyota runs better with NGK or Denso plugs/wires.

I used to have the NGK Iridium's that are $7/ea. Now I have the NGK V-Power since they are gap-able (the iridium's are not). I'm not really sure if there is a difference in power or how it runs since a lot more things have changed between using the two but iridiums are supposed to last 120k miles.

not gap-able? can you explain some more?

I know iridium have that special design tip that is extra small, but i figured you can gap them with a ramped gaping tool. Can't you gap them with another tool that wont damage the electriod.
