tl:dr - while I'm #TeamNovusOrdo, I'm delighted with the Angelus Missal
Most importantly, I wholeheartedly recommend purchasing from Latin Mass Helper site - Thomas and Bernadette are doing God's work, providing personal customer service (the way is should/used to be) while remaining competitive in product price and processing/shipping costs compared to vastly larger companies. Their support continues after the sale as I've relied on the website for information like ribbon placement and learning which Liturgical week it is
I may be the rare customer that purchased a Missal for edification rather than for attending the Latin Mass. I was born in 1961, so while I have vague memories of Mass during the transition from Vatican II, I am curious about how Mass differed from then to now. So, went down the rabbit hole in search of the best Missal for my needs. Thanks to the website, I was able to narrow my choice to the Angleus (with the Baronius close behind)
Initially, I was hesitant to purchase a Missal because of the cost (about the same as a good study Bible). I chose the Angelus 1962 because; 1) wanted a Missal that was closest to how Mass was prior to Vatican II, 2) wanted the most comprehensive resource, and 3) wanted to supplement my current Missal (the Universalis app on iPad). The Angelus checked these boxes. Within its over 1900 pages, there are Mass readings (I enjoy reading Douay-Rheims translation), prayers, rituals, Saint feast days, and so much more (most in both Latin and pre-Vatican II English vernacular e.g. Holy Ghost instead of Holy Spirit)
The Angelus is well-constructed, using Smyth sewn binding (thread, which is more durable than glue or staples), gilt edges (highly recommend that you flip through all the pages as they tend to stick together when first out of the box), and thin (though sturdy) paper. Though the cover is premium, I did shop elsewhere for a Missal cover as I prefer material (canvas in this case) over leather as canvas is easier to clean and hides fingerprints from skin oil so much better
Overall, a great purchase that I expect will become more valuable as the years go on
