I currently have two Lilja barrels; a 30" 1:8" 3G #6 on my .270 AI (2013 build) and 27" 1:9" 3G sendero on my .30 Lara (2016 build) and very pleased with them.
Two of my go to gunsmiths use quite a bit of Lilja barrels, the same is true with Kirby Allen >>>

Honestly, I went with what my gunsmith's recommendation based on my intended purpose, not to be mention supporting my local product.
The bottom-line, it's nice to have plenty of choices; I hope this does not turn into anything negative. We all have varying experiences, take it for what it is worth.
BTW, while he does not frequently post, Dan Lilja's son Carson is a member here and I'm sure he'd more than happy to field your questions/concerns. He has been very helpful on my last project build.
