Transferwise can be difficult too when it comes to limits. Like they might as for proof of source of funds at some point. Or delay a bigger transaction for 2 working days. I︀ also read they are OK for transactions worth of up to USD 7000 or so.︁ And I can see that being an issue from personal use too.
I would not︂ call that large volume transactions.
Revolut made me a little trouble (asking for proof of︃ source of funds, but after sending passport photo they have been cool about it). But︄ I did not move high volumes. I just like them for travel and virtual cards.︅
