Both last foreva, both sound the best!
Pick choice makes a huge difference, not only on your playing but your tone...IMO.
I used to like Fender med or heavies, picks long ago, they played nice, but they sounded like plastic, but killer for pick scapes. The downside is that they never lasted long.
Then it was Tortex by dunlop for a long time. I never liked them for pick scrapes and artificial harmonics and while they took time getting used to, the tone was nice.
Then I moved on to Jazz III's, nice but too damn small.
Then I moved down to mediums in the Cat Tongues, lasted forever despite pick scrape-hell, great tone, but something was not right. I seemed to over shooting while picking or something. Then I realized they were too light, unless possbly with an 8 guage, which I don't use.
So I bought all the heaviest, Cat tongues, the tone was different, a little more like a tortex, artificial harm. were a little better than the tortexs but not too much. But all in all, they were the best thus far....
Then after seeing malmsteen in Taipei and getting his pick from a tech?
I tried it out and freakin loved it. It was a Delrin 1.5mm. This pick is heavier than a Cat Tongue, but more in the middle. The outer edges are beveled and pick scrapes, were like a Fender Medium and they last forever like the Cat Tongues!
I found the heavey Cat Tongues and the Delrin 1.5mm totally killer for alt. picking and dynamics. Also, after comparing many picks using an acoustic guitar, they were also the best. That is, nice dynamic that isn't sharp followed by a long warm, natural sounding ring out. Many other picks, didn't come close. For example, pingy sounding or bright from the first dynamic then a hollow or bright ring that ended quite quickly in comparison.
