The eMMC for me is worth the price. Too many corrupt SD cards.
One nice thing about Allwinner based SBCs is the strong development community that mainlines support for their chips in short order. Few other chip vendors have mainline support, which makes their boards abandonware in short order.
Two things that are immensely helpful if you want a stable experience with the Pi:
1. A good power supply.
2. A good microSD card.
Most cheap power supplies (like those you get free with a phone) don't supply 2A or more consistently, which the newer Pis need to run stable.And as far as microSD cards go, [I wrote an article on that last week](https://www.jeffgeerling.com/blog/2018/raspberry-pi-microsd-... there's a huge gulf between the best and worst cards, even from name-brand manufacturers.
BTW, your link seems to end up on your front page, rather than the card comparison article.
Not a single issue with storage.
