That is a sweet boxset, I'm a fan of soundtrack inclusions as well. Severin is a great distributor, need to get more of there releases for sure, I only have a dozen or so.
For a first time watch I like to go with the English dub. After that I go with the original language and no need for subtitles. I definitely have that set on my radar. I love every Severin release that I own 💯👍
