Oral vs vaginal,which one do you trust more?

Sugar plum
Hi ladies, i ve been temping oral and vaginal this cycle. (Using Different termometers lol  but they are of same brand.) just to see whats best for me. patterns look mostly the same but like today's temps one went a bit higher from yesterdays (the vaginal) and the oral one went slightly lower then yesterdays. Which one would you trust more? Thanks and good luck
