Hard to quantify really I would say both.
Prayer can be as easy or hard as you make it (this is why the holy spirit helps us to pray) and reading the Bible can also be easy or hard (some people mke it harder than it needs to be) depending on how one approaches it. JEsus opened peoples eyes to scripture so ask for His understanding of it.
I would say without the holy spirit to help us neither is really possible on our own strength. Jesus would remark about the prayers prayed by hypocrites and the people that read scripture without even coming to Him so definitley there were people in his time that made a big show of prayer and bible reading i.e Pharisees and they were very religious but just couldnt grasp that God wants those who worship him in spirit and in truth.
Mind you the Pharisees did not have access to the scripture of the new testament at the time. For us, the new testament is a gift written down for us since Jesus is in heaven now interceding for us. It is a love letter from beginning to end. Note that the Old Testament did not have any personal letters instead its many narratives, psalms, wisdom and prophets warnings! Notice that Moses didnt write or include any letters to the israelites in his five books. But Paul wrote so many! As did Peter, James and John.
Our God is one who wants to communicate and Jesus makes it all personal. Instead of addressing the entire Israelites as a group as Moses and the prophets has in his day, one gets with Jesus one on one encounters. jesus said when you pray go into your closet and pray to your Father unseen and your Father who sees you in secret will reward you.
With so called popular spiritual leaders they pray so much out loud in front of others with long words that they may think their praying is enough to get by when actually God doesnt even hear them. They only pray so that they can be seen by others! Check out Proverbs 28:9
One has to approach prayer with a clean heart...you are addressing our Father...think about it is it easier to communicate with Him by talking so loudly that everyone else can hear and eavesdrop or is it better to go to Him when its quiet and one on one.
