Looking at an 01 ob with the 6 cylinder. Will that be more reliable than the ej25 that just blew the gaskets?

speaking very generally - yes. It is true the EZ30 is not reported to have hg problems as often, they also are less common so, the actual difference in RATE of hg problems is not easy to quantify. But the impression is, the 6 cyl gaskets are more robust.

 

BUT, the older a car is, the less important it's brand/model reliability when new - and the more important is previous care and current condition. A properly regasketed EJ25D could be more reliable than a mistreated EZ30.

 

ANY 14 year old car could be a ticking time bomb.
