One type of prayer may predominate but we shouldn't feel that we have to pray in one way only. All ways are valuable and can be God's will for us at a particular time or stage in our relationship with Him. We have to distinguish between the objective best and subjective best form of prayer. In all this it is important to continually search for where the Holy Spirit is leading us in prayer. Above all, we need to remain flexible in our relationship with God.
Rigid beams break while more flexible ones only bend.
Allow God to mold and direct you.
