Cost is the most important stuff. Rest all not so important. Unless you are sending money to bangla/nepal/indon.
2nd criteria is obviously speed. I take cost over speed anytime anyday. After all what's the hurry?

For funds you can forget about using card. The only provider who give you credit card to pay is Bigpay.

Supported destinations for funds (bank, eWallet, agents, cash out from ATM) + ease of funds collection, again unless you are transferring to bangla/nepal/indon. Then by default it will always be bank account. If you want cash, go find your local moneychanger. Many moneychanger have options for cash on delivery. Then again with Bigpay who needs cash unless you are in bangla/nepal/indon.

For ease of use for sender I am online person. Hence I like my stuff to be online. Forget about wasting time and money looking for carpark. Everything settle with a click of the mouse.

Network strength
What network strength are you talking about? The countries they support or those places for you to collect cash?

Transferwise, instarem, moneymatch. Have your pick.

Avoid western union. Is among the most expensive. Good if you want cash. But avoid at all cost.

Avoid. Exchange fees cannot even beat those fintech companies.
