Not Ranked
In a nutshell?
Dot 3; Mineral based, will absorb water, will eat paint.
Dot 5; Silicon based, will not absorb water, will not eat paint, higher boiling point than Dot 3.
Dot, 5 does have some drawbacks besides cost. You need to have a specific reason to really need 5 over 3. Just my two cents.
