I fix and assemble stuff professionally, and I've used almost nothing but AS5 for years and have had nothing but good results out of it. I've also used quite a bit of Shin-Etsu stuff over the years and always found it to work well too (it's been my second choice when out of AS5).
Why he skipped AS5 in the review is beyond me.
Same here, I've used it for like forever and based on many factors it's still my go to thermal paste. I don't like liquid metals because of application difficulty, cost and corrosion. AS5 is great and cost is reasonable, I especially love the fact it doesn't dry out (or at least not for a very long time).
