Developpers opinion doesn't matter much, but developpment cost and reliability does. If a project takes 6 months vs 3 weeks, it's a completely different game.
Even for big B2B corps, it's the difference between a project you can lead on your own and get credit for it, or something that will go upper in the chain because of all the approvals you need for it.
In a previous life, to get an Adyen contract and dev. environment and then the prod credentials, it took us something like 3 months, and we had a smaller PSP integrated for a different project in the meantime. That meant that for any project we didn't have as much volume, we'd go though faster PSPs instead of reusing the Adyen connection.
