You’re posting in a Mojo 2 thread, so you’ll probably get responses that lean Mojo, but here we are. I personally think Chord’s DAC/amps are incredible value, and have always preferred them within whatever relevant price band to the competition. I own an original Mojo, and Hugo 2 myself.
I don’t have a ton of experience with ifi DACs, but generally think ifi makes products that are a great value as well, and do own other ifi gear - so nothing against them at all.
To give my usual, incredibly unhelpful advice: There is no right answer. The best thing you can do is to listen to both and pick the one you like. If you can’t do that, make a reasonably informed decision and just enjoy it. Neither option is bad, and no sense fretting about whether you would have liked the other 3% more.
