Both scores are accurate. There are only 3 criteria that go into the production of a Fico score:
1 - The Fico scoring model being used (Score 8, BCE 9, etc)
2 - The bureau data being used (EX, TU, EQ)
3 - The moment in time the first 2 pieces of criteria above are being used together
The score you are getting from Experian is probably your EX Score 8. You can also get your EX Score 8 from MF. If you are comparing both of those from 2 different sources, criteria 1 and 2 above are identical. That only leaves number 3, the moment in time that the scores were generated as the reason as to why you're seeing two different scores. If you look on the screen where you're seeing your EX8 score from Experian, what date does it say? When you look at that EX8 score from MF, when is it dated from?
Two scores generated at different times may be drawn using different data, as credit report data is constantly changing. What you'd have to do is look at your credit report from the time the first score was produced and compare it to your credit report from the date of the second produced score. The more current score is going to be the "better" one, as it's more recent. The older score isn't "wrong" it was just produced from what is now old report data.
