DOT 4 is better than DOT 3, in terms of going longer before needing new fluid to flush out the moisture and rust. I use DOT 5 (silicone) because I don't like rust, flushing, and ruined paint. I don't find it "spongy" like many claim, most of whom never used it. DOT 5.1 is not silicone, it is just the first glycol fluid to meet the 5 rating. All brake fluids are synthetic and have always been, so don't pay more for that claim.
