will think about it next time as I ended up using Changehero for this purchase as they ended up having the best ratio and that was what I was looking for
Rates can change, sometimes Coinswitch gives you better rates than others, sometimes Flyp.me gives you that. I'd rather say I have 5 options of instant exchange that I can use if I need them, rather than this or that is the best one.
Most of them are similar, you don't have to register on most of them, so it's not really an advantage.
