After more research the reef angel seemed just as expensive after a number of modules, and maybe more complicated

As expensive after modules .... probably.
more complicated .... definitely.
more capable and more reliable .... absolutely.
Like anything in life, you will get out what you put in.
The reef angel requires more tech skill/ learning curve.
The profilux requires more money.
The apex/reefkeeper requires less and you get less.
Good luck with your decision.
