Exactly. I signed up with stripe maybe 5 years ago. At that time, I was trying to find a processor, and came close to signing with a bank. The bank wanted me to sign a long-term agreement, the agreement had disadvantageous and confusing terms with unclear costs, and it was more expensive than stripe at baseline. The sales process was really sleezy: I only discovered all those terms because I read the contract carefully before signing.
Before that I used two other processors, both of which had a confusing mix of monthly and per-transaction fees.
If you are a very, very large business, maybe you can do better than stripe. But if you are small or even medium size, I am skeptical there is a better deal out there.
