Way better than PayPal Xoom!
I love this service. I've been doing a lot of international purchases, and was first using Xoom through PayPal. Many of those transactions were declined for no clear reason. Wise doesn't do that.

I've been able to use Wise to transfer funds quickly and without worrying whether the transaction will go through, and I'll have someone waiting for funds that never arrive (like with Xoom).

If you're looking for something better, use Wise. I have done quite a few transactions now with no issues. I only took off one star (would do only half a star off if I could) because you need to enter the recipient's address, which feels invasive. Most strangers don't want to give out personal info like that. Besides that, I've been really happy with the service.
