So what's opinion about Shorai batteries after few years of usage?

Pretty good. I killed my first one, my obd2 reader would kill the battery since it sucked a lot of current so if I forgot to unplug it the battery would die after a few days. It handled dying maybe 5 times over the course of a year or two, then permanently bit the dust.

Then I got another one I think a year ago, this one Ive discharged I think once and it's still going strong.

As long as I don't leave stuff plugged in sucking current it hits just as strong if not stronger than the stock one, even after sitting for a week or two.

If I kill this one I'll buy another one so I guess that's a pretty positive review.

ROFL that's the same thing that happened to me. It killed my first battery, and killed 2 alternators (from the low CCA and high strain after a couple days of sitting) before I finally figured out it was that damn ODB2 scanner hahaha... live and learn I guess

why the alternator got dead?

I would only drive it on weekends, and sometimes every other weekend, during the winter months. The battery would drain to the point where the car would turn over "okay" but was definitely a lot more sluggish. So the alternator was doing a lot more work having those extended period of bringing the battery back up to 100%. They're not really meant to do that: charge the battery hard and run the car.
