I've used (Transfer)Wise multiple time sin the past. I recently moved to Revolut though. Seemed easy enough to send money to family and friends (small amounts) on a recent trip. I like that you can have multiple currencies held, so withdrawing cash from an ATM in Ireland one day and in the UK the next was no issue.
I have a link to invite others to Revolut that I am happy to share individually (PM me). Of course I'll get a kick back for that.
