If both get a 4.8 (and there are enough votes for it to be reliable), probably both are good. The things you can do to decide:
1. Throw a dice
2. Don't trust the numbers only, but read reviews also. Which one is strong on the points you find important?
3. Buy both and see if your personal opinion is 4.8 for each also, or maybe one is 4.7 for you and the other 4.8 or 4.9. .
