If I may, I'd rather prefer a translation layer like Wine, but for Android. Thankfully, it's in the works. Soon™.
I do expect that Waydroid's stocks will increase tremendously as Valve's Lepton is based on it.
As for your query, it depends mostly on your sensibilities:
- Waydroid is lighter and is ever so slightly better integrated.
- VB offers superior sandboxing (and thus improved security).
FWIW, I've had better experiences with Waydroid, but your mileage may vary.
I foresee a future in which (so-called) sysexts will be used heavily to address the resulting gaping hole. Unfortunately, it's not perfect either...
Though, I have to say that I find it quite hilarious to see how many alternative package managers are required to replace traditional package managers.
